What will help is if you list anything that you may have changed recently.

Rather than assume and attempt to help you via text. I’ll drop this here. It’s easy to read, comprehend and a must for new and seasoned mikuni users. Good luck!

fyi: don’t let anyone tell you that 42 mik is too big for an 883, it can be tuned for it. I ran a 48 mikuni on a bone stock 883 just to prove a point.

Invest in an extended pilot air screw that can be tweaked by hand when you're out on a run .Same goes for the idle adjuster . Much easier than trying to use a screwdriver on an engine that's jumping around .
