    Dual sxr mikuni 40mm carbs on 750sx.. Jetting?

    I've had 550's and 650's for almost 30 years but totally new to the 750 motors.

    I've got a set of dual sxr carbs for a '92 small pin 750sx motor thats going into a650sx with a Factory Pipe 750 Limited exhaust.

    I'm at about 2000 feet elevation but may be going down the the gulf occasionally.

    What N/S, L/H jet and pop off should I setup the carbs with??
    If you're not crashing, then you're not trying!!!

    Ski situation in limbo!

    Special thanks to Chris Newmiller, and Mitchell at M&M Marine!

    I had that setup but with a PJS 650 pipe at whatever altitude phoenix is at and I think I was around 70/145 on jetting.
