    Exclamation Fuel Pressure For Kawi Ultra 250x?

    What is the best setting for the fuel pressure regulator on the ULTRA 250X.

    I Have all the stage 1 from r&d. But need to know the best position ...I`m setting it at 37psi.. and its running 72mph with full tank of gas. Would like to know if that number is ok..

    yes the 72mph is ok. Fuel pressure correct is dependent on a/f ratio being correct. 37 sounds good, but I can't tell you if the a/f is good
