    Yes ! With room to spare at the top, but the 900 exhaust will hang about 1/2 inch lower than stock, you need to run 750 carbs and "brains" ECU.
    If it's a 1981 motor, you need to plug the tach drive hole (oil leak)

    Dibs on the bad 900 motor? And welcome to XJBikes Greg!

    I got a 900 Engine that's almost finished that I need to sell.
    The Jugs are honed.
    The Head is Machine Shop fresh with Valve Job and Seals.

    Finish putting it together yourself: $450.00

    Built: Labor and Parts (Needs rings for the 2-hole and wrist-pin clips)

    I guess that afterburner takes care of anybody who likes to tailgate or just get-up close to you and flash the lights wanting to pass.

    What's more amazing- - the total lack of gear, or the inability to touch the ground while revving the wee out of a 10,000 HP engine, while doing burner pops?
    Seca 900 brakes doing their job !

    This guy's carbon footprint is ALMOST as big as Al Gore's ! :eek:
