My best at the track is a 21:307, today I done 21:312 which sounds bad (2 grassy moments), but my nearest rival was on 20:306 and he said the track was slow, so maybe it is better.
Swap the rear belt tentioner left for right. You can tighten the belt more so it wont slip. SP belts stretch more than the kit ones
