My timing is set correct, it has been running awesome for a while now before I decided to try the 750. I really think it is a carb issue and not timing at all. With the size of the cam, I know we had to crack open the secondaries a fraction on the 650 and it ran great. I think I may have opened the secondaries to far or I know the back float was set to high and I wasn't able to adjust it before the plugs got fouled up. Somebody told me if the float was too high in the secondaries, and the secondaries were cracked open a bit then it could of been sucking fuel causing an extremely rich condition, which in turn fouled the plugs out. I should start with new plugs and a new powervalve for starters right. And lower the rear float, it was just at the top of the hole before I realized it. Thanks, Erik
