    An old thread but

    Hey
    Reading this... I’ve just done a blow thru that’s fully adjustable (fuel AFR) when riding.. saves a shit load of time pissing around with jets.
    Also have automated it to self adjust about 2 times a second all for bugger all $$
    If anyone interested feel free to ask.

    Fuel injection would be nice but this is a early 90’s poverty pack.
    I guess nobody can be shagged now days to turbo a carb bike....

    Are you going to spill?
    a servo stepper motor operating a carb needle driven off a 02 sensor and a light bar scale?

    Bloody close. Super pitot. Cheep ass modified boy racer boost control to bleed excessive pressure. Driven off o2 sensor . Was bang bang but at the moment working on PID.Arduino and data logger..
    Ultra effective and cheep as chips. Just dial up fuel afr req . Did some landspeed trials with it in manual and worked sweet as.. Auto has made the thing angry as... taken away the shitty big fuel up as boost building

    Great suff i would love to see some pics of the set up i are assuming you used one of the needle jet air bleeds for the adjustable pitot that quite spectacular who came up with that as its a stroke of bush rigging genius.
    i was thinking maybe you had a steeper motor on a SU needle from your description.
