    How to tune carbs?

    Just completed a handful of mods. What is the the proper way to tune a 1200PV? I took Oside Bill's recommendations on jet size and settings, and the ski starts easy and runs fine. A slight hesitation upon first giving throttle from an idle though. Perhaps that's normal, this ski is pretty new to me. Anyway, when tuning am I looking to achieve highest rpms at WOT? I have a tiny tach hooked up temporarily and I'm topping out at about 7040 most of the time. Should I try running a bit leaner and a bit richer to see how it affects the RPMs?

    Ski is as follows:

    2004 XLT1200
    Riva heads 145 psi
    Riva S2 stinger
    Tau Ceti arrestors
    125 high/117.5 low jets
    Solas 13/19
    R&D plate and grate
    Free flow exhaust

    Fasted recorded with gps was 64.3, but 61.5 is more common top speed.

    Not sure if the 2004 is like my 2000xlt 1200, but once I disabled my accelerator pump, the ski took off perfectly from idle. Very simple to do. I used Cajun Dude's site to get a good idea what was involved. I removed the cam.
