My new 4 Stroke now has smoke!

I'm looking for advice from anyone who's been into a WR450 motor or has and idea of what I might be looking for. I sank my 04' WR450 last weekend and it took on much water. After limping back home, flushing clean oil through it three times, and running it for short periods it's now smoking when you gas it, and is making some detectable noise from the top end. After removing the valve cover and visually inspecting it as best I could, I cannot find any visible damage to the Cams, cam chain or sprokets, or valve tappets. There is still some grey sludge in the valve cover, but lubrication seems good. I don't see any visible evidence of metal in the sludge. Plug is wet with gas upon checking it, but no oil. I figure the smoke is either from oil around the rings or valve guides. This bike only has 450 miles on it so I'm hating to have to go into it, but I want to make sure the motor is ok and fixed right if it has to be torn down. Any idea what might be causing the wining noise from the top end and the smoke when throttled. The bike cranks great, and has plenty of compression. I do plan to compression test it.

After I sank the bike, I rode it maybe 5kms back to the truck, then immediately changed the oil, but by then it was too late, the damage was done.
Good luck with yours, hopefully it is not as bad as mine was.

It's amazing how quickly the muddy water gooped up and has set in every part of the engine. Sure wish I'd moved that breather hose sooner.

You'll have to let us know how you make out with the teardown, and again, good luck.

Thanks again for the info!

Even if I had a good shop in mind, I doubt you would want to ship your parts 4000kms to Alberta.

I'm in the process of doing that mod now.... now that I'm done winterizing my sled.
