625cfm street demon

The "fatter "I jet it the harder it pulls and the better it idles. The plugs are starting to get a light tan color now. I think I am going the right direction.
A little off topic but did you have to use the demon carb throttle stud or did the one from your previous carb work? I ordered same carb a couple of days ago but don't know if I need to order the stud also while I am waiting for delivery.
Yes you need the throttle stud and you need to split the carb to put it on. I found out the hard way and had to take it back off the engine.
