[terret725]

this is what i have. 2000 sxr new rings, read spacers, PI center dumps, 2 layer gasket removed center layer, clucthed 89l's with 2.4(i think) in only hole, YSY spring, stock 47* and 60* twist, runnin at 8100rpms, 144 studs and 388 dirt bike screws in the lugs, fett brotehr transfer rods at second from last line of full transfer, limiters out with a 1/4 of thred left, un updated center viper shock with stoffer spring, stock rear( may have a 46prx race ohlin back in soon). i weigh 140. top gear 20(stock 22) bottom stock.

just ordered a new 8dn after my old one killed my secondary adn blew it. NOW even after the pipes and clucting my buddies F6 is still beating me maybe it was the bad belt but i dont want to take any chances next time i race him( sick of teh yamie bashing). so does any oen have any treekin posiblities i can use to take hime on the lake. plus could i sue the airbox mod just for a race and tape it up afteward for normal riding if i used 1/2 bit inted of 3/4 or 7/8? Or any otehr little tricks or tweekin i can use to beat him atleast oncen then i wont ever race him again just incase lol. plus the ice drags are coming up teh 28th a few people gave me some tips liek soap on teh hyfax or phazer hyfax. any other ideas for them?

thanks in advance for any advice
