Hello, afew eeeks ago i bent 3 valves and thus having to do a bit of a re-build on my bike. anyway i put in 3 new intake valves, all new guides & seals. also, a new cam-chain and cam-chain tensioner. i should also point out that earlier this spring i put in a new piston, rings, and cam chain as well. anyway after i got the valves put in and this and that, i put it all together, took it for a ride and the thing just isnt what it used to be, power-wise. i took it for a short ride and wasnt impressed, the thing wont wheelie, and its lacking big time in the power department. it runs like a top and the motor is tightet than a ticks ass, but im dumbfounded and dont know were i went wrong..any ideas? if u got a question ask it, i need some help! thanks!
