Well, since you asked-yes the new Team Xscrammit motors are ready!!! I just installed mine and it started soooo easy. I am sure it's gonne be the best cuz crammit said it was gonna be the best. I opted for the MEGA BORE setup which utilizes KeithBlack pistons so my cc's ended up at 1852cc on a 2 cylinder motor!!!

I say the pics are bogus, as is this thread, you don't own a Superjet and those pics are fakes, everyone knows Yamaha 701's are paragons of reliability and never break, just ask anyone.

it actually does look more like deto than a needle bearing. you're right. if it was a piece of metal of some sort it wouldn't just be concentrated on the outer edges of the piston and head. also, apon closer inspection I noticed that the "pitting" is more of a small "crater" shape than a "jab" from a chunk of some type of metal. so yeah, I'm gonna go with detonation, and it looks like it was caught just before total melt down.
