Thanks also Venice.
Kev, That's unusual for the Opti-2.
I too run Opti @ 100:1 and do not have the problem. In fact there is little to no oil residue from the mufflers of any of my bikes. I'm wondering of that muffler you're using has anything to do with it but I don't see why it should. As long as your engine is running good and the spark plug reading is saying things are okay, I wouldn't worry too much about it.
