    In a word, no. You should be easily into the low or mid eighties on the FZR. Might want to get with one of the Riva techs and see if they can pinpoint why your top speed is so low. For starters, I'd be looking for a boost leak somewhere.

    needs more revs
    both should be about 8,500 that is where the safe point is
    not too many revs to hurt stuff but enough revs to make boost
    to give you an idea
    i was at 8,200 revs with C1 wheel and 13/23 impellor 81.4 mph
    changed to stock impellor 8,650 revs (on limiter) 83.4mph (on limiter at 75% throtle)

    I have this same setupmin my FZR and running that same speed. First I am going to adjust my AFR and hope fully get some RPM's from this. After I am sending my prop to impros to get it repitched. I have the same prop and I was thinking maybe the prop that was sold to me as a 15/23 was actually bigger because of inconsistencies due to mass production. I would also do this if I were you. I will get these stuff done and write back.
