I'm working on tuning in my 19mm PHBG. My idle jet is rich, and I'm getting boggy throttle response and low end (part of that is also not having my clutch tuned right, but whatever). As I turn the little adjuster screw (not the idle speed screw, the mix screw) in, it runs better.
My question is, I know you need to re-jet your main jet as temperature changes. I was wondering if I'll need to re-jet my idle jet as well? If so, I need to get more of a range of idle jets.
