The mapping on our bikes (if I understand the maps
http://www.bonnevilleamerica.com/forums/...part=1&vc=1 ), both 790 and 865 is designed to retard the ignition at higher revs. You could do an easy test just to satisfy yourself by climbing a hill at lower revs (just barely above lugging the engine) and listening for pinging (detonation).
A subject for Greybeard to weigh in on for sure as he has a much higher developed understanding of all things cam and timing related.
