yep first track day after freash rebuild and mint tuneup

3 laps in coming from top of 6th gear (at 12000 rpm)
down to second gear into hair pain,, just coming out noticed
a rattling sound then i started to pull over, the power died and when the bike stope'd the rpm died out, i try to kickstart but the leaver wouldnt move, so i assumed (in a gutted state) that it seized..


took bike back to work and droped the bottom cylnder , luckily there was no damage to cylnder sleeve and there was oil also in the mix,

although when looking in the head TWO BRASS PIECES came out along with
shards of metal, the piston is also damage around the edge but rings seem okay, also there was a E-CLIP in the head also,

the connecting-rod has no play (foward backward) but does have play to the right side as it looks like a spacer thingy is missing beside the con-rod

im guessing its the thrust bearing washer?? cause my mechanic said that thats the only thing coper or brass looking in the engine

NOOOOOooooooo! after about 3-4 thousand bucks this happens on my third lap at the track@!.

anyone know wat i should do, iwhere i should look,

im really screwed guys. any help much appreciated.
