M&M gurus need help!!!!!
I've read all the posts I could find on the air bleed screws, got some questions so I may better understand, all that I can find says 1.5 turns from lightly seated. But from the factory sealed mine were like 3 full turns out. I guess I just want clarity. I've done a lot of work to the bike to get it running decent, upgraded ECM and tune, red injectors, exhaust, intake and filter. I have a small stumble at idle and I know as bad for it as it is, I can't blip the throttle. That's where it had a slight stumble, other than that bike pulls hard.

I wish I could help....but Ive never messed with the factory set air bleed screws. I would imagine they would be setup like the two idle mixture screws at the base of a two barrel carburetor.

When you get both idles set to where you want them, pull the 5 and 15 amp fuses behind the right side cover and leave them out for 30 minutes. It's a funky EVO voodoo ritual we all do. Suposedly, it's so the ECM can forget and relearn the new idle settings.

I looked in the 1998 and 2001 Factory Service Manual. I didnt see anything regarding the bleeder screws in either manual.
In fact.....the 2001 manual is nearly useless regarding the EFI system. Where as the 1998 manual has quiet of few pages dedicated just for EFI.
Any rate....nothing there

Read my 97 as well again doesn't say much about them at all. But again service manual really doesn't do much for performance mods

Ive looked at Screamn Eagle Instruction sheets regarding Stage 1-3.....Air Filters, hot/cold idle, ECM cartridge flash, and red injector swap.
Nothing there either.

They are similar to mixture screws in some respect, now I've read up on all the forum has to offer, but no one ever seems to have confirmation, I've read 1.5 turns from lightly seated. I want to know why mine were 3 full turns out and love you asked what they do, if I had a better understanding it would help with the performance mods that are on the bike currently
