Question about 1986 Honda CB 700 SC Nighthawk
Sounds like no timing advance. Will seem to go well up to about 55 or 60, but will run flat or even slow down above 60. Follow shop manual procedures for verifying timing advance operation. If you watch the timing mark with a conventional timing light, you will most likely discover the mark will not move when you rev the throttle. If this is the case, you must replace the electronic timing pickup or module. Consult shop manual for the correct procedure.
