I figured out my keihin oko main jets will work on this dellorto carb, it had a 95 and I went up to 105. Switched to a uni filter and now I'm getting up to 50mph, might even try a bigger main jet. I still need to work on getting the idle a little higher, the idle screw is turned all the way in and turning it has no effect. Changing the needle clip position hasn't helped either, looks like it's running rich at idle so I need to order a smaller idle/pilot jet.
I've been learning as I go with this dellorto carb but this scale helped me get a better handle on it.
