03 shee right piston Detonation

[670eddie]

from the right side of a 2003 banshee and it was running good all day long. probably 30-40 hours on new pistons. also the rod bearings gone too on the right side. the Dealer rebuilt both carbs . when this happen it was being ran for about 6 hours with cool down times here and there. just wanted to hear thoughts on what you guys think caused it.

piston crown looks pretty freakin clean......so either you cleaned the shit out of it....or it appears that it may have run lean....possibly from an air leak. Look at your plugs also......does that side look like it has small silver bits on the electrode? Did your plugs back out at all? Not only does it appear to have leaned out and detonated but the real big chunks on the bottom (of the pistons top view) looks as if it could have been caused by your rod bearing doing the cha-cha smash and dance on your piston. Either way you had to split your cases......make sure to clean EVERYTHING good.....as little metal chunks can cause chaos....as you already know.

Yes the Plug has sliver on it and we found that the big end of the rod bearing had tons of play!
