My buddy was out riding sunday...and calls me saying to bring down a battery becvause his is dead! So i take the battery out of my Shell-of-a-raptor and go down, and it still won't start wit a new battey. so we take it home, and find out that we can't turn it over with a wrench at the flywheel, and tehre is a clanking sound. We then take apart teh top-end (me knowing in my head what is is) and what do you know?? Connecting rod snapped, took out teh piston, cracked the sleeve, and pounded the valves! and i thought having my tranny blow 4 times was bad. HA. He is currently getting a new 03. I told him like 3 weeks ago, that raptors with high-comp, and cams do this.,...i am very worried about my piston is mine also! good thing i'm sellen err 4 a shee!

 

that sucks, have him measure the cylinder clearance please

 

Once again, was this a stock bore with hi comp piston??? Also with your trans I assume you kept putting in 01 gears?
