    the motor is a simple swap

    controls are different but I belive connectors are the same just check to see if mating wires match tank swap possible see the thread on that

    if both are yics motors the tci is same.
    atari guages need atari wiring but there are a few people looking for then here
    if both are maxims rims will swap you couls convert 650 to dual disc unless it is a seca then it has dual discs


    Fuel tank interchange information

    The big questioon is, which 650 do you have?
    I'm assuming the Maxim from your avatar.
    The other biggie is which 750.

    If the 750 engine is fom a Maxim.
    If it's from a Seca then there are (relatively easy) modifications that need to be done to the motor mounts, unless he wants to solid-mount the engine.

    Does this mean that you really want to have a 750 instead of a 650?
    The things that I would swap are the engine, the forks (maybe), and the fuel tank. Nothing else is worth the effort IMO.

    Yes I was thinking engine forks and of course the front tire, question will the exhaust work with the 650 engine

    Yes it will, but if you swap engines you'll not be needing the 750 exhaust installed on the 650 engine, since it won't be on your machine anymore.

    That depends on whether the 750 engine is from a Maxim or a Seca.
