xr650r popping at idle, deccel

completely new to jettin four strokes :naughty:

2002 xr650r powerbomb header pipe opened up, runs fine when on the gas

Bike is hard to start and backfires/pops alot at idle, letting off throttle, and deccel.

Lean popping right?

so should i-

go with a bigger main jet

or

adjust the air/fuel mix

or

raise the needle a clip????

or

a combo of the 3?

really just trying to get it close because next week it'll be on the Dyno getting massaged into purrfect carburation.

thanks for any help :naughty:

Mike
