engine problems

[crazyriles]

I have been having serious engine problems with my mx bike this whole year and my mechanic and I cant figure out what it is. I run a full dasa engine using a web 208, crf ignition, bored out fcr carb, 13:1 piston, etc. Well the bike has ok bottom end but has awful top end. I cant pull holeshots on it but i can pull holeshots when I use my woods bike (just has pipe/cam). On the straights my mx bike gets beat by piped yfzs. My clutch keeps going out so we keep replacing it so if anybody can help me please do Im tired of spending all this money on repairing it and trying to find out whats wrong.
Thanks

Clutch is probably slipping in higher gears. Buy a complete clutch setup from Honda and 1 extra friction- replace inner plate and judder spring assy with the extra disc. Use new springs!

When racing, always check to see that you have the proper clutch lever slack before each race!
