I only do practice days for fun weigh 15 stone and am in need of more power. im currently using a rotax max engine, which i find runs out of revs easily. reliability is a big thing for me as i like to spend as much time as possible on track and not in the pits. been looking at KF1/2/3 class engines also 100cc options, all of which can be picked up at reasonable prices. can anybody tel me:- how much power/max revs/average running hours between rebuilds these varoius engines produce. Any other info/advice would be graetly appreciated
ps should i just buy some high octane/oxygen fuel aimed at karts and stick to the rotax max ?
cheers
