    Hi

    I have this CB Sevenfifty, RC42, its a 93 model, like all 90's CB750
    it has 73 ponies. I know the CBX750 had this engine, the CB is based
    on it, but is detuned, the CBX had 91 stock ponies. I've cross checked
    engine data, and everything is the same, except for gear box, the CB
    has 5 gears, and the CBX has 6, and the cams are different. the Carbs
    are also slightly different. Unfortunatly i do not have a spare CBX
    engine, otherwise i would just pop it insde the CB frame, but i do
    have the camshafts and a set of carb fully functional. I need to know
    how to have these bits inside the CB engine, and get the thing running
    100%. Does anyone ever did this thing??? i know there are at least 2
    german CB owners who did this, but their reports are vague and the
    email addresses are no longer active.

    thanks

    Gus

    Put it in, turn it over by hand, if it doesn't lock up, viola!!! it works!!!
    If it locks up, either get out the angle grinder and remove the offending metal or just give up
    and go back to the original camshaft & carbs.
