Hey guys i think i know what i did wrong here but i would like some input. Replaced Crank seals and bearings. used yamabond to seal cases, and used a little bit on the reed cage. i dont have a air leak tester but i did the oldschool can o carb cleaner around everything and didnt see any change. this motor ran beatuiful and idled nicely too.
First time out after breakin i did a few plug chops and the plug had a nice cofee tan, but i think my jetting was off. It soft siezed after a few quick blasts at wot. it unstuck and then kept running. i brought it home and then did a compression test. i still had 130lbs, but exhaust side of piston was smeared and so was intake side. Cylinder is savable since no gouges just scuffs. piston was destroyed.
im running FMF Fatty pipe. Stock Silencer. No lid with a unifilter. TDR Reeds. Cylinder Kit. I got a 290 jet in there now. is it possible that i need to go to like a 350 or so? i think this is where i screwed up. i live in ny. and also the needle was on stock clip setting.
it also had a strange knock jut off idle when u would get on throttle and get off. its NOTHING internal everything was to spec. its more of alomst like a decel detonation. Should i go back and check my stator timing?
Its been a while since i messed with 2 strokes. Im a 4 stroke guy now but missed having one. just want some input. thanks
