    Thoughts on piston wash?

    2001 gp1200r
    D plate
    Premix 40-1 full synthetic

    I have ran 3 tanks of fuel since the rebuild. I purchased the ski with a fresh rebuild and immediately went premix and jetted. I think its running just a bit lean on all 3. What do you think? Click image for larger version.

    I agree with Rich(WFO) To me it looks to be JUST on the rich side of perfect, which is where you want to be. On cooler mineshaft air days you will be dead on IMO. I have an injected motor with 125hrs on it with slightly less wash and no issues. I recheck wash whenever I change motor load (new prop, nozzle, etc) and adjust accordingly.

    Thank you very much. I can look at pictures and examples all day but a second opinion makes me feel better. Thanks again fellas.
