    Need to cure popping on decel

    by 5 speed » Tue May 26, 2009 8:23 pm

    I have installed and modded based on all the recommendations here; bought a needle JD and think its 4th position, fuel adjustment screw(about 1 3/4 out), new main (think its a 165) opened the airbox, have a 450R silencer on it. Has the block off kit installed. Once warm it runs good but I think it might need more fuel around mid way and when on the gas and rapid off lots o popping and you can see some fire on a video clip I had.

    Suggestions on what to try next????

    Open the fuel screw to 2 to 2 1/2 turns out and test.
