I’m ashamed of our kart!

After we raced at the start of December, the plan was to strip the kart, clean it and wrap it up for 6 weeks or so. Because I really don’t have the room (or the lighting) to make a proper job of this in the garage, the ability to do this depends entirely upon the weather. Factor in Christmas and a holiday period that consisted of exactly one dry day spent repairing storm damaged trees and I have to confess the kart has been untouched in over a month. Until yesterday.

The kart was dirty but I didn’t think it was wet and I didn’t expect to find quite so much rust on the axle, with spots forming on the bumper and seat supports. Worse, my expensive Panther chain was starting to rust also! With the wife working the weekend and two kids to entertain/taxi around, I wasn’t able to spend more as much time as I would have liked on it but I was able to strip the back end and clean most of it up. Wire wool and T-Cut got rid of all but the toughest rust spots on the axle; I could probably have gotten rid of the remainder had I not been working to a ‘pick up the wife from work’ deadline. To make myself feel a bit better about the neglect, I polished the chassis and bumper 🙂 Just need to do the same for the front half of the kart and change the brake fluid and we’ll be in a better position to consider karting again!

A karting Christmas

Happy New Year!

We had an interesting Christmas this year (ok, last year) in so far as the kids normally still manage to come up with a long list of things they would like despite reaching or being near teenagers. This year was different – for the first time Junior had a list with next to nothing on it: an engine and Gran Turismo 6!

I had been considering getting another engine for some time – I wanted the reassurance of the backup engine should things go pear-shaped on race day and, if I was going to get another engine, I wanted one with a CNC barrel; the majority of racers have them, several engine builders had recommended them so I had decided that would be what we would aim to get. If I am honest, it wasn’t essential and you could make a strong argument that we may have been better off investing the money in more track time. I should point out that I am not assuming the engine will suddenly close the gap between us and the pack (honest!!!) and I know that most of the time remains in his lines and consistency (although there’s likely a big chunk in my setting up of the kart for wet conditions) but you pay’s your money as they say…

Junior was just expecting some money towards his engine – I had pretty much drummed into him that, if we were to get an engine, he’d be getting cash and very little else. He had some money left over from the Great Star Wars sale of 2010, when we had sold off the Star Wars toys he had been collecting since he was 6 on eBay just before Christmas and made £1,000. Advice: always take the boxes of collectable toys from your kids and put them straight in the loft! He still had half of this remaining and my wife had agreed to let him put this towards an engine with Santa donating the remainder 🙂 Between Santa, ourselves and the extended family, Junior got the engine and also a kart trolley (we picked up one of more sturdy folding variants with tray and tyre hangers in very good condition for £50), some long front and rear hubs and a new nassau and front spoiler (ahead of his birthday in March when he’d like new decals).

So, in the absence of any new toys (isn’t it a shame when they stop wanting toys for Christmas?), Junior spent most of Christmas playing GT6 (it is pretty good, by the way, although he mostly kicks my arse royally when we compete in the time trials!) and I am  hoping the new engine does prove to be quicker than our current one. I have to admit, I’ll be more than a little disappointed if it is not!

Total spent so far: £5,264

End of first year accounts!

Ok, so when I posted my predicted costs at the start of the year, I had reckoned on this costing around £3,200 based on ten practice days and no racing. A full season of racing would have cost £4,600. Going back through my posts, I noticed a few costs had been missed so with two sets of used wets, a set of used slicks, a carb rebuild and a few miscellaneous items thrown in, the grand total for the 2013 spend (12 practice days, one aborted practice, 3 race weekends and a race Sunday) was £4,594!!!

It broke down something like this:

Retirement package (chassis, engine, new slicks, used slicks/wets, trolley, Mychron 4, remote starter, transponder, kart cover, rib protector, spares package – carbs, pods, bumper, seat, fuel tank, nassau, floor tray, track rods, stub axles, exhaust, axles, sprockets, chains, nuts/bolts/spacers etc, chain lube/brake cleaner): £1095
Trailer/Tow bar/lid: £490
Helmet/shield protector: £345
Tools (tyre tools, file, hex keys, socket wrenches, spark spanner, tyre spanner, sprocket puller): £133
Clay Pigeon Loyalty card: £40
Practice Days (12): £385
Race weekends (4): £233
Petrol for car: £273
Petrol for kart: £126
Stuff (pedal extenders, cargo net, ActionCam, lead, half share in awning, waterproofs for mechanic): £192
Consumables (pulse pipe, fuel pipe, tank filter, funnel filters, cable ties, lubes, cleaners, chain guard, sprockets, chains, break fluid/seals, engine mount/clamps, hose clips, screws, bolts): £277
Repairs (chassis weld, engine, steering wheel, spark plug, cap, ignition lead): £213
Rebuild (1 engine + 3 carbs): £250
ARKS starter/test/parent license: £152
Used slicks x5: £190
Used wets x2: £100
Used SE rims: £100

A really obsessed blogger would link the above costs to the relevant articles but I am above all of that 😉 So what do you get for such an investment? 103 laps of Dunkeswell, 96 laps of Llandow (which always comes out as Lladnow when I type it) and 1,692 laps of Clay!!! Not to mention *a lot* less sleep, the onset of greyness, some crushing lows, some amazing highs, an awful lot of fun and some experiences with your lad that you’ll never forget 🙂

Have a great Christmas!

Race 4: another forward step

This weekend was our final outing of the year – at the Clay Pigeon Kart Club Turkey Trot. A weekend of 6am starts for one final time this year! You know how I hate it when the kart gets soaked enroute? Let’s just say you wouldn’t know I had cleaned it the week before from the dirt it was covered in by the time I arrived at a sunny Clay.

Saturday was a really good day – we had a mixture of damp and dry tracks so a bit more much needed wet practice but, as the track got grippier in the afternoon, we looked pretty decent (especially after moving up to the gold restrictor – Junior could really feel the difference in bottom-end power). When the track was at it’s quickest, we were just over 0.5s off the pace but it was the first time Junior had been overtaken by one of the quicker drivers and then stuck with them rather than watching him sail away – he even looked like he was going to have a go back!!! 🙂 We’ve had a few false dawns so I didn’t get too excited – race day often reveals the starker truth. The kart got soaked again on the way home which meant I spent the evening drying it 🙁

I really didn’t want to hear the alarm ring but I kicked myself out of bed at the usual time. We had our clearest ever run to Clay – a grand total of 2 cars were in front of us during the entire journey. And it didn’t rain 🙂

The warm-up was good – the track was easily too wet for slicks even though there had been no rain for some time. If it’s going to be slippy, I would much rather there wasn’t a dry line so that the tyre choice is easy. For us, with used wets, we don’t have the risk of writing off a £160 set tyres so the borderline calls can sometimes play in our favour. It was only a warm-up though. Heat 1 was ok too; disappointingly there were only three of us racing – two of this season’s front runners and Junior! We were continually losing ground but only finished 15s and 10s behind over the 12 laps. Heat 2 was probably the one that was a little disappointing although it was probably my fault –  we were losing over a second a lap pretty much the whole way through although Junior’s race wasn’t helped by his fuel tank bolt falling off and then him completing the final laps holding the tank between his knees!!! I normally wrap velcro around the tank to stop if moving but, for some reason, the velcro had spent the weekend in the boot. I think the biggest problem though was me running a much higher pressure than was called for – the tyres had gained 3.5-4PSI during the race and you could see that we weren’t using as much of the tyre as we should have been. Tyre pressures are the hardest thing for me to gauge – especially in the cold/damp conditions. One to put down to experience…

The track was now dry so we switched to a full dry setup and I thought I would move down a couple of teeth just to experiment – we were going to finish last anyway so I wanted to see if Junior felt a difference. Then it rained! Although the track did dry by the time of the final, I didn’t have time to replace the sprocket so we had a lower gearing on a damp track, slicks on a wet setup. My reasoning was it wasn’t dry enough for a full dry setup but slicks were essential so I did what I thought was right. It didn’t turn out too badly though – we lost under a second a lap, so although we were 19s and two thirds of a lap adrift at the end of the 20-lap race, it represented a decent step forward over the weekend, especially compared with our last race. We’d learned a bit more about setups (with a lot of thanks to my rival TKM Dads, who took pity on me on probably shared a lot more information than they would normally!), Junior had been able to improve his lines a little, the Alpha Timing system’s lap stats were very useful and we’d had an enjoyable weekend.

So our season is over. The engine is in for a rebuild. The kart will be completely stripped as soon as I get a chance and we’ll take 6 weeks off. Unless I get the chance of a drive with a few of the other TKM Dads early in the New Year… 🙂

Cost of weekend: £24 petrol, £13 fuel for the kart, £35 practice fee, £49 race fee

One year on…

This weekend just gone was one year since I naively took my first steps into 2-stroke karting. I had been talking to the Clay Pigeon Kart Club folk about getting Junior down to try out a 2-stroke kart. In my mind, it was nothing more than a chance for Junior to drive a fast kart after his Arrive/Drive exploits. It was a fun day, even if Junior was *ultra* slow – that’s him in the site banner photo – I always thought it made it look like he was ducking inside some seniors but the reality couldn’t be further from the truth! I had absolutely no intention of buying anything.

Twelve months and £4,255 later…

Surprise, surprise!

Eight tyres in an hour – sometimes I impress even myself! My fingers and quad muscles ache (the latter from shoving my knee into the tyre when putting on the new tyre) but that was an outstanding success 🙂  If Junior shows the kind of improvement on Sunday that I showed today, I can cancel the turkey order (the winner of each final this weekend bags a turkey!) 😉

The thing I hate most about karting…

If there is one thing worse than looking at a TKM engine that has ten hours on it, it’s the sight of eight tyres that need changing! Aside from having to stomach some considerable costs, the lows of troubleshooting when you are out of your depth, running without an awning in what seems to be one of the wettest locations on Earth and watching your lad ignore your advice lap after lap, there isn’t really much I don’t enjoy about karting 😉 That is with the exception of changing tyres: everybody will tell you it’s easy – and they certainly make it look so – but I *really* despise changing the bloody things. Getting them off the rims is easier than putting them on. I don’t think my technique is far off and I have actually changed a set on my own but I fail more often than not – I just don’t think my office-boy fingers are built for it!!!

So it’s Wednesday, I have three evenings to replace our practice and race tyres (with more used ones, of course) for Clay’s end of season Turkey Trot and I’ll be spending tonight sat on a dust sheet on the kitchen floor, hands sticky with tyre paste, fingers aching, sweating profusely and cussing at nobody in particular!!! Now there’s a picture you won’t be seeing…

Practice 13: just what the doctor ordered

We came away from our third race day with mixed emotions – the kart had run smoothly and Junior had enjoyed himself but I was hoping that we might have been a little closer to the pace than it turned out we were. We started racing having reached the point where we were roughly a second off the pace but we hadn’t looked close to that kind of pace on race day. Although I know that race day is obviously a different kettle of fish to practising, the leaders were putting in the same kind of lap times you’d expect but we weren’t getting close to our best times. I think it is just all part of the learning process: I am definitely off the pace when it comes to judging the right pressures for the tyres (it isn’t quite a simple as it was in the summer!) and Junior definitely still has much to learn.

With all this in mind, I decided we’d head back to Clay for another practice day – it would give Junior a lot more seat time than he’d been getting on a race weekend and a chance to work on finding the time that would get us back on track (so to speak). I’d picked up the carb that I had had rebuilt for the last race day but forgotten to collect. The weather was pleasantly warm (for November) and it made a real change to turn up at Clay to see not only blue sky but a dry track!!! After the first session, Junior was already quicker than he had been a week earlier and it was nice to see him putting in lap after lap. It also gave me the opportunity to walk around the track and have a look at his lines – it was invaluable to see what really is happening out on track and provided plenty of little things to work on (although you could rightly question what do I know!).

The sessions were really pleasing – there were a couple of quick Junior TKM drivers on track for Junior to try to keep up with and he managed to nudge his times down from 37.3s to 36.6s, which only put him in the region of 0.6s off the pace. 194 laps was more than Junior had ever done before on a practice day and he was visually quicker by the end of the day and getting a much better exit out of the Top Bend. I know I have said this before so, whilst it was really pleasing, I’ll be cautiously optimistic about any potential improvement in our race pace.

Cost of day: £12 petrol, £7 fuel for the kart, £35 practice fee

Costs since last outing: £20 carb rebuild

Total spent so far: £4,255

Race 3: um… a trifle disappointing if I’m honest!

Remind me to write these posts up a bit sooner!  We had our third race last weekend; as we had had to test the Saturday before to ensure our motor was ok, we missed the practice day and just attended the race day. I was very keen to see how we fared in the dry conditions – we hadn’t really had a chance to gauge our dry pace on a race day and Junior had looked pretty good in difficult conditions the week before. Although we are all at sea in the wet, I was optimistic that we may be in sight of land on a dry track.

As usual, we set off later than I had hoped but still got to Clay quicker than we ever had before :O so were track-side at 8:15am and scrutineered by 8:30. Interestingly, we got our first scrutineer comment: he thought our brakes were a little iffy! That was a surprise as we’ve never had any issues and Junior has been really happy with them of late (I’ve checked them since and they feel ok!). Race mornings are always a little misleading – you think you have plenty of time before the warm-up until you realise that the sign-on and briefing take a good chunk of time. We were looking good until I found I couldn’t prime the carb – this was a new one! It was good last week but it just wasn’t allowing any fuel through. Annoyingly, I had taken our bad carb in for rebuild during the week and had completely forgotten to pick it up!!! I put on our second carb (which had been our best one until our problems at Dunkeswell), primed it with no issues and it started fine.

I sent Junior our for his warm-up and took my marshalling position (I can’t stand watching from the pit lane so sign up as a pusher and stand on the designated marshal post). It immediately obvious that something wasn’t right: we were properly slow, as in two thirds of a lap after three laps slow. Junior came in and said he just had no pick-up from 10,000rpm. I didn’t need to hear this – a return of the revs issue and around 45 minutes to solve the problem wasn’t good. I got the non-priming carb out, replaced the gaskets, sprayed the gauze filters and put it on the kart. To my huge relief, it primed perfectly 🙂 To the races…

The kart started perfectly and Junior’s start was good; there was a coming together going into Billies that Junior had to dodge and he was in touch exiting the Hairpin but, between The Horshoe and the Top Bend, we seemed to have lost a fair amount of time. This set the scene for the day – I watched Junior gradually losing ground and finish 18s behind over 9 laps. I was a bit deflated at this – I was really hoping we’d be 1.2-1.5s off. Although my experience with getting this tyre pressures right in sub-optimal conditions is limited, I was pretty certain we were in the right ball park. We just seemed to lose so much ground in certain parts of the track, I couldn’t help but feel we just weren’t getting the lines and braking right. Junior complained of oversteer so I brought the rear width in by 20mm.

Heat 2 saw Junior get a ‘great’ start (he didn’t look last as he crossed the line!) and us narrow the gap between our fastest laps and those of the leaders (from 1.95s to 1.65s) and we finished 16s off the lead. That was encouraging – Junior felt the rear width change had made a good difference although, disappointingly, everybody else finished 😉

I decided to do a little testing – I took a tooth off the rear sprocket even though the Mychron suggested it wasn’t necessary to see if Junior felt a difference in either his exit or top speeds. He didn’t and posted an almost identical fastest lap. He did however get to have a race with one of his friends who had left the track in questionable circumstances and rejoined as Junior was passing. He was pleased to defend his 7th place 🙂

The final was notable only for the people leaving the track when trying to heat their tyres up!!!. Unfortunately Junior got collected and ended up down the bank on the exit of Billies. Not sure what the marshalling regulations say but I sprinted across the track to get him back but, with three karts off track, I figured we had to do whatever necessary to get the karts back on track. Unfortunately for me he was down a slope and, rather than turn the kart around and drag it back up, I was initially trying to push him up the hill with the back end lifted (also know as ploughing!!!). Another Dad helped carry his kart onto the track and he got going in time to join the second formation lap but his tyres were caked in mud :S At this point the karts had slowed ahead of the start and it meant Junior driving around with little chance of cleaning his tyres. He lost a lot of ground on lap one – almost certainly because of the mud – and was 22s adrift after the 11 laps. He set his best time of the day (37.52s) but was still 1.6s off the pace.

So we’d had a decent day running-wise, Junior had had another great time but the day, for me, was a bit of a disappointment. We were 1.5s off our best lap, although that was obviously in much warmer conditions, the leaders were probably 0.7s off their quicker times. We were again running on used tyres (they had probably done 50 laps) so that might account for a few tenths but I think there is still a lot of time to be found in our lines – it’s hard to gauge when you are viewing from a fixed point on the track; whether Junior had gone from taking too much speed into his corners to killing too much speed, I don’t know. I feel the need to get down to a non-race weekend practice session again so that we can get a decent amount of track time to try to figure things out. I realise that things will improve over time and with experience but, if I can accelerate that process, then I am all for it.

Cost of day: £12 petrol, £6 fuel for the kart, £23 race fee

Practice 12: Engine test

I picked up the engine from the builders on Friday: he had had good look at the electrical side and could find no issues – the thing sparked every time. The crank misalignment had been resolved and some bearings replaced. My wallet was £138 lighter but more concerning was the uncertainty this left us with over the state of the engine and it left me with a decision: practice this weekend so that I could check the engine out or next weekend on the practice Saturday before we race. No really a choice, huh? It meant that the kart, which I’m a little bit ashamed to say had gone untouched since Dunks (I know… but you know I am usually *very* prompt at cleaning up), was going to need a fair bit of work done to get it ready. In the evening. In my dingy garage. With minimal lighting (even the street light outside my garage was broken!). Fours hours later and we were pretty much good to go – it was bedtime and I had barely seen the family although that seems to happen a lot since we bought this thing 🙁

Saturday – we were two miles from Clay when I realised I hadn’t actually checked to see if the track was open for practice!!! *Never* do this! Luckily, they were only two vans there when we arrived: there definitely was no event on 🙂 The track was bathed in the kind of glorious sunshine for which Clay is renowned:

If view when arriving at Clay October through April!

The view when arriving at Clay anytime from October through April!

There were two problems to begin with: when you are wanting to test a motor that has a suspected electrical issue, you really want to be able to test the spark. And for that, your starter really needs it’s battery, which I had left the battery at home on charge! Next problem was the flat tyre on our trolley: I hadn’t sorted it out which meant I’d be spending the day pumping up the trolley tyre between sessions. Ho hum – on with engine testing…

The kart started first time and we kept the kart to below 12,000rpm for the first session. That went smoothly and I pulled Junior in after ten minutes to let the engine cool and make sure all was well. The second session was hampered by a ‘feeling’. Junior has these from time to time and will drive straight into the pits and report them! Sometimes I really wish he’d just spend another lap trying to identify these ‘feelings’ although there are times when I wish he would just STOP THE KART IMMEDIATELY!!! You can’t have it both ways I guess 😉 It was time for slicks anyway so we took the kart off to check it out. I couldn’t find any real issues although the chainguard was knocking on the finger guard and he has objected to his side pods being too loose before so I tightened those a little. Typically, by the time our next session started it was starting to rain. Junior stuck in a handful of laps before coming in complaining about revs again. This was becoming a pretty big issue – he had reported it at Dunks last week and I really could have done without it becoming a persistent issue. It was raining pretty heavily now so we covered up the kart and sat in the car for an early lunch (scoff all you like – I bet you have an awning! ;)). Keen not miss two session, I got my waterproofs on an got the kart set up for the wet. The sun was shining by the time I had finished :-]

Anyway….we looked a little off the pace in the wet. I think fundamentally Junior doesn’t have the confidence to push as hard as he needs to. It’s one of things that comes practice I guess. It was a pretty windy day so, once the rain stopped, the track dried quite quickly. Junior was never going to be setting any PBs today and his revs never really got much above 15,000rpm but his lines *really* improved over the course of the afternoon – he clearly had a lot more confidence when the grip was there and I couldn’t really fault what he was doing (consistency excepted!). He looked pretty quick, which was really encouraging to see. I’ll be doing a Sun Dance on Saturday evening in a bid to keep the rain away – I am quite keen to see where were are in the overall scheme of things (I’ll be going by how many seconds off the penultimate finisher we are!). We had the odd problem – Junior came straight back in complaining something wasn’t right and, when we looked at it on the trolley, the engine mount bolts were loose and the chain had much more slack than it should. I think I may have only hand tightened the engine restraining bolt – I should be above this now 🙁 but at least I didn’t lose the mount brackets and bolts. The revs issue also raised it’s ugly head again although I think we might have solved this one – after changing the carb, he said it was fine for 15 laps before it happened again and he came in. At this point I noticed that the fuel was pretty low and, running a 3l tank, I am wondering if the fuel is moving from side to side around bends and we are starting to get air into the system. We kept the tank topped up and had no problems thereafter. Consider this a tip 😉

Of course it had to rain when we were 20 minutes from home, just to ensure I spend three hours rather than one tomorrow cleaning up :/
