today when i was practicing for my upcoming harescramble, i was about an hour into my practice and i started losing power and all of a sudden to thing just shut down.....so i pulled out the kick starter and it was hard as a rock, so i was like d*mnit!

Got it to the shop to tare it down and saw that the spark plug wasnt all the way seated in the head so i un screwed it and aluminum shavings fell out. I got to looking at my piston and the piston had completely fell apart in the cylinder. now i need a new sleeve,piston,and rings.

I figured that since i have all of this apart i shopuld go ahead and put the 240 kit in it, but then if i do that i couldnt race the AMA races i have planned.

 

that sux at least you may have time to fix it. good thing it did'nt happen at the scrambles. good luck

 

The only thing that sucks about the big bore kit is that they build too much heat for an air cooled.
