I hear all sorts about 80:1 and such,but it says,clearly,on my Sherco,2%(50:1), and it runs great.Why wouldn't you run the recommended mix? Don't tell me your BS about carbon,that's part of the two-stroke deal;love it or leave it!I think people are only thinking about the burn; what about the bearings? If anything, I'd want more oil to the bearings on a two stroke.In my opinion,they're barely surviving as it is!
