    Did you check the links to the CJ-3B page on the F-head hop up from the FAQ already?
    http://www.earlycj5.com/tech/engines/index.shtml

    That sums up the max potential most likely.

    Solex is a good place to start for smoother idle and better throttle response.

    I'm not the one that said it. ;)

    Allthough I do recall saying it in another forum a long, long time ago.

    Turbo or SC would do more good IMO.

    Where you need the "Power" is on the hiway usually.

    Not just in short bursts.

    hey billy i would think you would want a "wet" system not a "dry" one in a carbed vehical since then you can put even more NOS in without going lean

    billy i know from my go cart racing buddies that the guys who run the 125 yamaha 2cycle motors that some of them shoot NOS into the fuel. makes a BIG flame come out of the exhaust. and big go.

    i guess bigger jets would work but then wouldnt you be rich when not on the button? ( this is from someone who does not understand a carb at all. never had one before)
