    V-Tech 8375 201 Tune Air Fuel numbers on 2012 rxtx

    Ski has been stuttering down bottom so I got some air fuel numbers at idle and slight throttle, tomorrow I will get wide open throttle, seems very lean. Mods are- 4inch air, riva cooler, & prop.so far this tune needs more fuel down bottom or maybe add bigger injectors?

    Idling around 14.0 is acceptable.
    Let it fully warm up, then take readings every 500rpm and record.

    If it begins to lean out, don't continue.
    My original v-tech map would spike to 15.6-15.9 (sputtering). Not good. Many, many adjustments later and I'm sitting pretty.

    +1 I know they recommend the VT1100's but, at 8375 you're 48's should be enough. Could be you're stock fpr. RRFPR may be needed to get static PSI. Did you change plugs first(<--had to ask)?
