Also checked throttle safety switch and kill switch
I have not taken reeds out nut I looked in there with my scope camera and they look good, also didn't mention when it does get to higher rpm the tail light flickers, also when the hood was on the tach needle would bounce around.
Just pulled Reeds out, both are not chipped at all, and experience in voltage regulators going bad?
At what RPM is this happening at? The 4 coils can be swapped around as they all fire at the same time. Did you try new spark plugs? Have you made any changes lately bars, handwarmers etc? If so start there checking wiring for damage. Check all grounds and put dielectric grease on all connectors. Check the wiring by the fuel tank something tells that was an issue on some machines. If you cant find the problem try bypassing the tss , kill switch and ignition switch( not all at the same time) and see if it changes. Warmers off etc. Do all your lights work head light and tail light etc. Did you check for correct measurement of the exhaust valves?
