Rebuilding Top End?

Recommended Posts

Well I just wanted to get a final opinion if I should throw in a new piston and rings or not. I have 31 hours on the bike but its of hardcore racing. The bike still has great compression and starts first kick but im thinking its good ensurance to finish out the season on. I already have the piston/rings and gaskets so.... Yeah any last words?

Yup I did one on my 04. I figured it was a good thing to do since I had the parts already and I dont want it blowing up on me racing. Im happy though, the valves are still mint.

you should be able to completely remove your engine from your bike completeley disasemble it clean all the gaskets replace all the seals touch up the intake seats replace the crank and piston replace the engine add all fluids load it into your hauler and have it at the track by 1.30 this is if the track is only an hour away and you start @ 8 in the morning and this also inclueds drinking 2 cups of coffe so whats holding you back just do it.

It is done. I scared the crap out of myself. I couldnt sleep so I was working on it at 5 in the morning and when I went to go put the cam back in, Im guessing it skipped a bunch on the bottom gear so when I put it back in it was out of time. I went to turn it over by hand just to make sure everything was cool and all of a sudden the kickstarter jams and i hear a clank. The valves were hitting the piston. :thumbsup::ride: So yeah so I ran upstairs and passed out and then got it all back together this morning. Purrs like a kitten.
