Our 2015 shakedown

Although we made an early start to the year in a borrowed kart, it was really good to get Junior out in his own kart at the weekend for a shakedown ahead of the opening round of the club championship next week. Having had the chassis stripped right down for a respray (that I susbsequently deferred in favour of touch-up), it’s always a welcome relief to see the thing remain in one piece! I had spent a good chunk of the Saturday trying to get my action camera optimally fitted. The Sony HDR-AS30V has so far seemed like a very nice piece of kit but it is woefully let down by Sony’s lack of mount options: No tilt mount was available at release date and when they did attempt to correct that omission, they produced a tilt mount that lacked full 180 degree movement, opting for one that rotates in 30 degree increments (which sucked on the nassau) 🙁 So I had bought some M3 bolts and rubber spacers in a bid to make something that at least worked for me.

It was a wonderfully sunny day considering the time of year. The track was already dry and grippy at 10am even if there were patches of frost remaining on the kerbs. Our first mission was to run in the practice motor. On the recommendation from my builder, we shortened the run-in time compared to the process we undertook for our race engine; Opting to spend a 10-minute session at 11,000rpm, 10-minutes at 13,000rpm and then a final 5-minutes at 15,000rpm. Running in after a full chassis strip was a good thing since the kart wouldn’t be worked too hard and I could check over all of the nuts and bolts whilst the engine was cooling down. After that we got on with our goal for the day: Improving Junior’s lines.

We’d talked about this. I don’t ever criticise Junior’s driving but there was a point a few weeks back where I told him that he needed to up his game if he wanted to compete this year. I’d be perfectly happy to carry on as we were if he was going to be happy finishing towards the back of the pack but, even allowing for some incompetence on my part, there were huge savings to be found in his driving. He didn’t like it at the time but I pay a lot of money in support of his enjoyment of this sport so, from time to time, I say my piece and expect him to listen to it! We walked the track first thing and agreed that we’d work on getting The Dell sorted. It is an important corner at Llandow, especially for Junior as he tends to lose time in Sector 1 so is often under pressure here as they enter the main passing zone.

Things went pretty well for us, lap-wise. Although the track was disappointingly busy so there were two groups of owner/drivers (2-strokes and 4-strokes) in addition to the odd arrive/drive session, which meant that we only got in 61 laps, Junior worked really well to the extent that he lapped within a tenth of his personal best time. The camera worked really well, the mount didn’t snap (for now) and the Alfano continues to impress me. Video footage of one of his sessions can be found on YouTube although I still haven’t mastered the quality loss that YouTube’s encoding process seems to inflict and I have no idea why I am the only one who can view the video at 1080p 60fps :S

Sony video footageWe had a couple of mishaps: one of Junior’s friends wanted to try our kart as he had some issues with his own but he only got in two laps before the chain snapped. Not really sure what caused it – I’d never had a chain snap until we got a shunt towards the end of last season, when we lost our reliable Panther chain but this EZ chain lacked the longevity (and just as I was singing the virtues of our switch to Silkolene chain lube after two years tolerating the mess caused by my purchase of a job lot of tins of Rock!). I hadn’t realised that the Alfano wasn’t switched on so we don’t have any data to suggest whether or not the engine revs went through the roof. Following this our day ended prematurely when, in plunging temperatures, Junior lost it on the out lap and snapped the bumper bolt. This did annoy me, probably more than it should have, especially since I had put the tyres up for a test without forewarning him!

Cost of day: Practice fee £40, bridge toll £6, fuel £10, petrol £10, new chain £20

Total spent this year: £757
