Sorry been without a computer for quite some time have not had a chance to get on here. So how would i explain to a machinist how much weight to take off without throwing everything out of balance.

your going to have to split the cases and examine the transmission to see what gave.

I have a 02 400ex with stage two hot cams, port and polished head, 11:1 Wiesco high compression piston, open air box with k&n filter and i run it with 110 race fuel. Jetted to run with all these mods. Is there anything else i could do that would increase the performance of the bike without going big bore? I mostly do trail riding and some track riding and the dunes when i get the chance.
