    Piston Wash Pics. Let Me Know If Lean Or Rich

    Since Randy from watcon is out of town, I need some in put on this piston wash. I am trying to dial in my carbs and just want to know if I can go leaner. I have a 2003 octane with novi 48mm. It is jetted at 115L 120H 95G spring. Let me know if I should go to a 115H or what you recommend.

    You're certainly safe.
    What RPM's are you turning?
    What fuel are you running?
    Pre-mix or injected?
    How many turns do you have the highs at?
    If you are roughly a turn and a quarter out, why not adjust the high speed screws in and then decide if you need to rejet.
    IF you had Keihins without high speed adjusters you could certainly go down a half size and run her again to verify piston wash.

    They are novi 48mm carbs. I just got them 2 months ago. The screws are at 1 turn each on high and 1 1/4 on lows. It is premix. I am running 180 psi. I also run half 110 and half 93 octane with amsoil interceptor. I am also running around 7000 rpm on the tach.
