Your jetting is off man, you need to get it squared away before you tear up your engine. If you are running an oxygenated fuel you will need to bump your main jet up about 3 sizes to accomendate for the extra oxygen. I would imagine that the octane of the fuel has something to do with the jetting too. I know if you are running alchol you need to run a much bigger jet for it to run the way it should.
I haven't really run high octain fuels in any of my quads so I don't know about the jetting, but I've run oxygenated fuels and alchol before so that's why I offered up some info on that. Hope it helps.
