Can someone help me with a belt issue? I have it geared 20 tooth rear an 19 tooth front for overdrive, an my belt became loose or thats what I thought. I had the tensioners fully tightened an it was barely enough to keep the belt tight enough. So I bought a new belt an put it in an it is no tighter then the old belt. I still have to run the tensioners fully tightened to keep it barely tight enough. Anybody know why?!
