I'm trying to replace the stator on my 2004 buell XB12s. I've taken off the primary cover and now I'm looking at the primary drive front sprocket. This is connected to the camshaft. When I turn the main nut that holds the cover, the enter motor turns along with the primary belt and rear wheel. I was told i have to use an air wrench to take this off, but i don't have one and don't have an air compressor either. What other ideas are out there to help me get this off with just a ratchet?
