I have 2002 lowrider screamin eagles slip ons aftermarket cone air filter. it pops every now and then when at red light when I give it a little gas or just moving around in parking lot the idle seems a little erradic any suggestions

 

Set the air/idle mixture screw to 2 1/2-3 turns out, and bump the pilot jet up 1 size at a time until the problem is gone.
Shy of that, dyno tune.

Ok will try that

 

Yep, breather and pipes are the reason it's running lean.
