I'm out in the garage right now working on my bike (which appears to
have lost cylinders 3-4 over the winter).
The book says two things for you
1. Engine lacks power and overheats - Cause: Retarded ignition timing
due to ATU failure. Remedy - Check ATU.
2. Engine "Fades" while under load - Cause: Pre-ignition. Remedy - Check
grades of plugs fitted. Use recommended grades of plugs only.
Sounds like it could be the second one - engine is overheating and pre
igniting which kills power (and crankshafts).
Check your plugs that they match the recommendation. My book says: NGK
of Nippon Denso (ND); models: D8EA/DR8ES or X24ES-U/ X24ESR-U.

I forgot to mention on the last stretch home I tried it again at
