Hi all,
My team and I have some theories behind this but I'd really like to throw this question open to the forum and see what the more experienced amongst you make of it.
I normally race in TKM at Clay but have recently built a Prokart and am running in the EPS series.
The kart is a 2002 LRG and we're running two decent Prokart Engineering T1s on it with the timing mod done. The engines have good dyno figures and are the one positive factor in the equation...
We had plenty of problems at the first round (the worst being the axlemmoving by 7mm when under lateral load, causing major brake binding) but the kart also refused point blank to handle whatsoever. Pir times were well off the pace (I'm at 194kg and was doing 40.6s at Clay in F6 last year in an R2, but 43.1s on Sunday) and we were stuck with monumental understeer on entry. We brought the front out as far as possible and tried various widths at the back but to no avail. Admittedly testing time was short as we had problems with a bent axle throwing the outboard chain, but we did what we could.
Tyres were old but had plenty of depth left, and didn't seem unusually hard compared to others at the end of the race.
Front torsion bar was in, seat some way back (I'm very tall) but not all the way back (my co-drivers aren't!).
I'm running 96 link chains, gearing fixed at 20-66.
The kart has LRG standard 17mm front stubs with medium OTK hubs.
Any idea what might be causing our woes? The kart would understeer right through Billies and put me on the grass unless I braked stupidly early and crawled into the corner, and would wash outid-turn at the Hairpin and to a lesser extent at the horseshoe, effectively making us a sitting duck on the straight before the Billies nightmare started again.
It's odd as I was on the pace in the kart at Camberley during their winter series (although we did run on Mojos) and I was doing 41.1s in testing in it at Clay a few weeks back.
The kart lasers up fine incidentally so it's not bent.
I think it needs either meatier 17mm stubs and longer hubs or 25mm stubs and a new set of tyres, but I don't want to go spending money that I don't really have only to find I'm woofing up the wrong Acacia.
Any advice would be awesome :-)
