    I finally found a site to host pics (Bigthanks to insey :bigthumb: )

    here they are, I have pics of the cylinder as well but they are on a cd somewhere and I don't have time to look for them now.

    Now, what happend was the pin that holds the ring in place (the one that is pressed into the piston) came out and did this. I was told that it got too hot because I was using too low of octane of gas :bs: I never had any detonation! Now get this, when you look at the cylinder base gasket there SHOULD be two large coolant passage holes in it. The one we took off the bike only had one punched out SO one of the main water passages was blocked off, therefore I think that is what caused the bike to get too hot and cause that pin to come out. Either way I now run 110 leaded and 93 in a 50/50 mix to be sure.

    Ok, enough of my bitching and ranting about my bike, I just wanted to get the pics up for y'all to see. I can post pics of the gasket too if anyone cares.

    There is just a lot ofcarbon buildup on top of the piston. I was running premium 93 and yamalube oil.

    pssh, most bike manuals say they only require 86+ octane anyway. Saying you were running too low of octane is total BS.

    Oh and I meant BS that the dealer/mechanic/whoever would say you were running too low of octane, not that its BS that you would claim that :)

    It was wiseco that said my octane was too low (of course)

    Either way, its back together and running now so I am happy.
