sheerider1026 Posted March 16, 2009 Report Posted March 16, 2009 those look like stock pistons to me.. how much time was on this topend???? sometimes they just go once the piston/cyinder fir gets loose.. its just hard to say.. time for a rebuild.. Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 defiantly not stock we just put these pistons in not more than 2 months ago just did the whole port/4 mil new pistons shit all at once 2 months ago or sooner. and i believe they are 60 over. Quote
T_Shee Posted March 16, 2009 Report Posted March 16, 2009 which side was it that got trashed? proly a crank seal Quote
RUDEDAWG Posted March 16, 2009 Report Posted March 16, 2009 Damn! that looks like a lottal heat going on there, what do the tops of the rods look like? Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 right side...can't really see it too good but the left is fucked up a little around the rings. Quote
278 Posted March 16, 2009 Report Posted March 16, 2009 Alot of things could have caused that... over heating, something getting into the motor, I think detonation will also cause that Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 Damn! that looks like a lottal heat going on there, what do the tops of the rods look like? dunno the bike is over at my buddies house where we work on them at. but ya we were sure it is heat related. just didn't know what it was that made them do it. Hoping someone could enlighten us. Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 What is your jetting? i can't remember offhand ill have to check it out tomorrow to see. i want to say 205 but i can't member the other one Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 had him go check it for me 205 52 Quote
RUDEDAWG Posted March 16, 2009 Report Posted March 16, 2009 (edited) I am by no means a jetting expert but I have done it alot. 205 sounds WAY big to me given your mods and elevation. How did it run up top? Boggy? Also needle clip position is very important. I am sure someone with more experience than me will chime in and give you some insight. I really hope you didn't fry the tops of the rods! Edited March 16, 2009 by RUDEDAWG Quote
kodie Posted March 16, 2009 Author Report Posted March 16, 2009 205 to big for 1 carb? when i bought it from trinity it came with a 195 in it and a 198 and i think a 192. Quote

I didn't realize that you were a one lunger! My bad, but anyway, it looks like a jetting issue or improper break-in to me just my .02 Check out the jetting/exhaust forum, I think someone posted about what jets everyone is using on single carb set-ups.

kodie Posted March 16, 2009 Author Report Posted March 16, 2009 nah i broke her in good. you guys think running 94 instead of 100 or better octane helped fuck this shit up? my buddy thinks its the timing but a shit ton of people run +4 timing so i don't think it was timing. Quote
