Picked up an ATC200 a couple weeks ago to keep my 185S company.
When I bought it, it was running great. 2 weeks later, the float sank and the oil got diluted with gasoline. So, I swapped the float for a spare laying around and changed the oil. The guy I bought it from was quite insistent that he had run only synthetic for years, and that I should stick with synthetic blah blah. I like synthetic oil myself, but don't like to spend the big bucks on Amsoil. So I put in Mystik 10W-40 ATV, which I have run for 2 years in my ATC185S with zero problems and no smoke.
I fired the bike up and rode for about an hour. The next time I started it, it smoked like a 2-stroke. The smoke is not as blue as 2-stroke exhaust, it's more of a greyish colour, however it is definitely oil smoke.
What happened here? I know synthetic can creep past valve guides and rings, but supposedly it always had synthetic before. Also I switched the 185S from 15W-40 Rotella to the Mystik product with no ill effects.
I just adjusted valve clearances, though I don't think it will make a difference.
