BonS, the early 1000's (75-77) had the hot cams...the 78 got a bit calmer profile, and it went down from there. From what I have learned, a blower bike would have liked the 78 and newer cams.
Depending on how much boost that bike is putting out, it would be right around 100 hp.
Thanks for the info and correction. I've just been developing an interest, maybe I'd call it an itch, in these bikes and have a lot to learn about them. I didn't know that Honda was revising the engine's tune while keeping the displacement the same over those years. Good to know.
