Went for a ride today to test out my new 6 inch risers, 96 580 ext started great and idled o.k. after playing with the throttle extension adjustment then started riding. Got about 3 miles in to the ride and open her up full throttle and talk about no power and then all of a sudden just died. Couldn't pull it over until I manually spun the clutch. Pulled the plugs, the one looked good the other one was white (overheated?). got towed out and home and it is trying to start but won't. Checked the spark and it is good on both sides. PLEASE HELLLLPPPP.
