Hey Guys, 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. Thanks Again.
