    Step up one size in the pilot jet?

    I added a full DG exhaust, and a uni afilter with not cage. The Machine breathes super easy now compared to stock, obviously.
    I can not get it to idle at normal pace since I added these aftermarket goodies. Either to low, then it dies. If I turn the idle up, seems like it goes a little to high and it starts to idling on the main jet. There is no nice happy median. I am thinking it needs a slightly larger pilot jet. I went from a 35 to a 38. But I won't be able to try it till friday. I am hoping this does it.
    Anybody have any input on this? Otherwise the machine runs like the dickins'

    The carb is stock, rebuilt, and jetted with a 125 main on the stock bore, but freshened up with oems parts.

    Did you try adjusting the air screw?
