Yes, the newest rider in the JEB clan took his bike a'swimming, inadvertently cruising right over the pond dam and into about 4+ ft of water. I went a'swimming, too, to fetch the poor green machine out of the muck.
Got things apart to clean/dry/flush. Airbox, carby, intake pieces, exhaust, packing, front & rear wheels (drum brakes) - good to go. I drained/flush the transmission and it looks reasonable at this point but I'm sure I'll do a few more flushes after things are running. Magneto side was oddly very dry.
The thing that worries me is the crankcase. I've got the head/cylinder cleaned up. I used some cheap 2-stroke oil in an effort to fill/drain the crankcase a few times and it's better. But I can see some milky-white residue. Is there a good way to flush completely or is it something that will work it's way out while it's running? I didn't want to go shoving stuffing anything down there (not that it would be very thorough anyway) for fear of getting a piece of something down there.
Ideas? Am I worried for a good reason?
Any other tips - perhaps from someone who's been there before?
Thanks!!
Drowned the KX60, need tips

Jeb-my son did something very similar with his rm 60. But instead of dumping his bike in relatively clean water, he dumped it (airbox side down) into 2 feet of stired up muddy water rigth off the side of the track.
As I was taking the bike apart, I kept hoping I'd see some positive sign that water/mud didn't get very far into his engine. But mud got past the reeds and when I flippted the bike over, muddy water poured out of the crankcase.
I pulled the engine off the bike and flushed it 7 times with premix. I was concerend that mud or grit was still trapped in some of the bearings so I decided to go all the way and split the cases. I was glad I did b/c I did find a small amount of mud still in there.
My recommendation to you is if you go the flush only route, once you think you are done, do it a couple more times.
