    If it does not stall, you are doing fine. Max rpm is 3600. Wide open throttle in neutral. Mine seldom got over 3400--but the tachometer has been shot for the last 3 years--these days I don't know. Maybe I can find the adjusting screw so it wouldn't stall at idle.
    Also, (pardon the hijack) I think my axle seal is shot and tranny is leaking oil. Is this a big job to fix? Can I add more oil and postpone till winter?

    Rediscovered the top speed adjustment. My Ultra goes faster now. In the throttle linkage area there is a little metal tab that sticks up an an angle. With a pair of pliers or special tool--tilt it up slightly to increase top end RPM. Very sensitive--don't bend it much. You may wish to remove the air cleaner so it is easier to see and access. Clean the area with a tooth brush and solvent, (no, not your own, stupid!) And lubricate the parts now that you have it open.
