Got some intel on the issue causing the sled to run erratically. Some of you may already know this, but I'll pass it on anyway. The small nylon bag just above the clutch guard on the left side of the sled, contains (one) small square relay. Remove that relay and clean the contacts if it shows corrosion, apply dielectric grease and re-install. Apparently that controls the exhaust valves as well as other electrical components that will cause your sled to run poorly. Now I know there has been discussion on the other electrical component that looks like a woman's pleasuring device has been the problem, that apparently is not the issue.
