    Note the petrol squirt to start, E85 fuel, TPI
    Yes I also noticed this need to ramp up fueling at approx 70 degrees. Lucky there is a fueling graph in the LINK ecu specific for this.

    I understand that! was more of a thought knocked down in an execl. tried to make it a little more understandable. I might be completely off.
    However, not how intake temp is affected by different fuel mixes. maybe someone who can figure it out.

    EGT Tuning

    Is it possible to use a EGT gauge and a long road to tune the mid-range (slide, needle) on carburated 2 stroke? If one does not have ready access to a braked dyno and gas analyser.
    For example, doing a third gear run for ½ km with the throttle held at ¼ throttle then another at ½ throttle and then at ¾ throttle while monitoring the EGT temps?
    Or would I be better off doing the same runs as above but with plug chops?
    Compare Pornography now to 50 years ago.
    Then extrapolate 50 years into the future.
    . . . That shit's Nasty.

    Ratio 6, that is air/fuel ratio?
    You can run richer for more coolingeffect as methanol has a wider 'tunerwindow' so to speak.
    You are able to run way rich without loosing much at all.
    In aircooled engines this is a very good option as they need all the cooling they can get.

    And E85 is known to beeing able to give you 7-8% percent more power than ordninary pumpfuel, so that´s about correct.
