    New here. Looks like a good forum.

    Question: will 82 XJ 750 carbs fit a 1986FJ 600 motor? Trying to find specs and am coming up empty on carb size and fitment.

    Thanks if you can. :?:

    google will always be your friend. and it says Mikuni BS32 carbs.

    maxim uses Hitachi HSC32.

    so they'll probably fit. as a whole rack. i would guess they SHOULD work.

    others might have better information.

    The individual carbs, maybe, since they're both 32mm, but the jetting and needles would be radically different. Going from Mikuni to Hitachi, I'm not sure how you would "translate" everything.

    The whole rack, almost for sure NO, the spacing on-center between the carbs would be different.
    The 750's intake ports are bound to be further apart than the 600s.

    Thanks all. I was hoping I could find an alternative to the FJ 600's. I have an 86 FZ600 and am looking for bigger carbs, with minimum hassle. The FJ600 are a lock. Just finding them are tough. I have a set but one of the carbs is hashed really bad. Anyne have FJ600 carbs or know of another fit?
