ok, so last night my engine soft-siezed -- stopped dead at full throttle. i think the problem was caused by my swing arm pushing down on the muffler, thus loosening it. i could feel a little air leak coming out of it when i re-started the engine.
so today i took the cylider off and found what look like a couple little smears of metal on either side of the exhaust port. there is a pic attached of what it looks like.
i had to get it home, cause it was starting to rain, and i didnt really want to leave it on the street in chicago. it seemed only to have lost a little bottom end power, but not too big of a difference.
what, if anything, should i do now? i've never dealt with a soft seize before.
i have not done a plug chop yet, but i am running a 14/14 dellorto carb with a 57 jet and a snail exhaust. so maybe i need to mess with the fuel/air ratio as well.
any advice is greatly appreciated. thanks
