Buddy has a 98 Suzuki 1500 VL that's running rich on the forward cylinder. First clue was the black smoke when he hammers on it, second was the carboned up pulg. Bike has 30K on it and he says he can feel it miss under heavy load. Went and got new plugs but haven't tried them yet. Old ones looked ok except for the carbon on #1. Pulled the airbox, no restrictions or crud. Anybody know anything about these ? Or where I can get a service manual for this thing. Searched Ebay no help
Thanks
Dave
