RM250 Oil coming from exhaust

[jkent4]

I have a RM250 and I found burnt black oil oozing from the exhaust the other day after riding. It starts fine and it seems to have good compression. I read somewhere that it could be a broken oil ring. Could it be the type of 2 stroke oil.

Anyone else have any ideas?

its not a big deal at all. alot of bikes do that. you are either running slightly too much oil in ur gas/oil mixture or ur jetting is a little too rich

Jetting is to Rich.
