    Can anyone help with some settings for Daytona TwinTec TC88 ignition module, I have a 95" with Freedom Performance big curve radius pipes,  stock but later model heads, S&S 585 cams, 45mm Mikuni and Moflow air cleaner. Any advice would be greatly appreciated

    Need some more build specs.
    Are you running stock pistons ? Head volume ? Head gasket size ?
    Or an idea on cranking compression ?

    Ok, you should be around 190 psi cranking.
    I would start at #2 initial and #3 advance.
    Test ride and listen for any knock/ping when rolling on in upper gears around 2.5 - 3 k revs.
    if it pings, which it shouldn't, go back on the advance  by 1.
    If it's happy you could leave it, or sneak up on the Advance and test.
    What jetting are you running in the 45?

    Athe the moment the jetting is as it came, but I'm looking at dropping the main down 1 -2 sizes, and although it prob sounds odd, I feel the pilot could go up 1 size. Thanks for your help, I feel like I at least have a place to start, cheers.

    Dynoharley, if I get a chance that would be grouse, Sunday might suit better, perhaps pm me your mobile, cheers.

    Just wanted to give a big thanks to Dynoharley, for tuning up my bike on the dyno, it's a big ride, but more than worth it, he does excellent work, really knows his stuff.
    Thanks mate.

    Good to hear.
    Very handy man to know !!

    I didn't think it would handle that much timing. This is what 8,0 looks like.

    I'm running a 175 main at the momemt in the 95"/45mm Mik'
