The 18t wont hurt a thing dont let anyone tell you it will.
The AI dont help it run any better it just puts air in the head at the ex port and makes pipes blue and ex pop.
If when you adj the idle mix screws you can hear eng. change you are prob. ok on the pilot all though with stock pipes stock pilots would be ok
You should get carb balance stright after any carb work every thing you do could change it.

Thanks for the advice. It runs fine now at 125/42 with TORS and 2.5 turns out. the Jenks tuning notes say to shim, but not by how much, .5mm? I have a foam unifilter, rubber velocity stack and it pulls pretty good all the way to full open.
Here's a question, with the stock 05 Bonnie 790 needle in, what is the effect of shimming? More fuel at what point in the band??
On various posts Ive read, not to shim with 18 tooth front, or when riding two up.
Thx!
Dean
