    I have a 172cc Typhoon, Malossi cyl, 360deg manifold, 24mm s6 R/T carb, S6 air filter and modified reedblock.
    But i can't get that thing running. It idles normal, acceleration is littlebit hesitant, but pretty nice and after 1/5 throttle dead end, low power. Max speed 60km/h, then it starts to wobble abit.(hard to explain)
    I tried with 120main jet and 110 and even 88, but it seems to stay almost the same.
    My question is what kind of mainjet u have put on your maxi with bigger carb and 172cc cyl. or what suqqestions u guys(girls) have? Does it really need 140+ mainjet?

    Thansk for the help!:)
