was riding some new trails with freinds last weekend and came up to a small jump with water on the other side. since it was new to me i rolled it, right into a 4 foot deep hole as in chinese wheelie. needless to say, i stopped dead in my tracks and fell over. the bike stalled, sucked water and floated on its side for a few seconds until i could get it up and out. i kicked it over quite a few times with decomp lever pulled and i don't think a lot of water came out. since it would not start after that and a tow back to the garage, i replaced the plug and air filter and cleaned out the airbox. suprisingly (sp?)it started after 3 kicks, however it would not run past idle. so, i took the hole intake and carb apart, cleaned it all up and after re-assemble kicked it over with choke on. started with 2 easy kicks, very good i thought. after warm up, took it for a ride and all is well except now i have popping at deceleration. never had it after going to 50pj since i first owned i. i figured maybe an air leak but can't find it (plus all else seems to be fine) or pilot screw adjustment. i started at 1-1/2 turns like before the bath, then went to 2 turns. didn't make much difference. so the question is, could i have cleaned the carb so well that it needs a richer pj? i'm leaning this way since it starts much easier than before plus it was only 60 degrees and low humidity. or could i have damaged an exhaust valve if the cylinder hydro-locked. while being towed i slightly released the de-comp lever to clean the cylinder out some more and maybe get it started. i didn't feel any pulsation that may indicate a valve hitting the piston. btw, i did check valve clearances since it was apart and they were fine, one exhaust a little close to tight. any comments would be appreciated. ps, bill i know you will be reading this and i'm still planning on meeting you guys at rausch reek friday morning unless the above kills the bike before then. keep ya posted.
