    Man that rig is next level. Complete badassery!

    I assume it’s like a 125/250 GP 2 stroke in that it requires frequent re-jetting during a race weekend?

    Not really. I have always tuned for reliable power rather than max power. To win first you must finish.

    The reason I ask is I’ve always heard how much work a 2T is at the track, that it’s not a jump on and ride it bike like a modern 4T.

    OMG I'm drooling, I love RZ's, but this is in another orbit! What class does it race in?

    Ooof for fks sake! Where's this located?

    Given no PV on those cylinders how does the powerband hit?

    If the prep is done correctly at home and the porting is not excessive (like many are) they are no more work at the track than a 4T.

    V5, D Superbike, Clubman. Probably more modern classes but Clubman and D are the only modern classes I raced it in.

    Gainesville, GA. I was looking for better drive off the corners with this engine so I did not get radical with the mid-range so I could take full advantage of the drive. I've raced 2T s both ways and I liked this one better.

    Jim, that is a work of moto art. What would it take to make it street legal?

    Depends on the state you're in. In Georgia mirrors, full set of lights. Tag holder, Speedo, Horn, Sidestand, Insurance and a tag. I'm probably missing something.

    My scales aren't working but the last time I weighted it, I believe it was about 320-325.

    I'm in NC so same as GA pretty much. Does it have a generator to charge the battery and a wiring harness that you could connect lights into?

    hinshaw929 Well-Known Member

    Yes, it has a generator that charges the battery. No, it does not have a wiring harness for lights or accessories.

    Nice setup. I would love another RZ, but I already have 2 race bikes. Tempting though.
