Not that the cap is the cause of pops, but that's where i would continue ...first keep it running.

my bike had all sorts of epa junk, that I got rid of, it eliminated the 'pops'. Any remaining pops I got rid of by giving it more fuel with the A/F screw.

Did this just start to happen?

Might be time for a good carb cleanout.

A/F screw is the idle screw right ? i am sitting at 1100 do i want to go higher ?
I dont know the carbs on that bike, but on mine the idle screw is seperate then the A/F screw.

Did it always pop or just start?

There is a screw on each carb. It's usually 2-2.5 turns out from 0 that we suggest.

I think you may have a clogged vent....it could still be in the gas cap OR the vent line exiting the bottom of the tank. check to make sure you get airflow through the nipple under the gas cap all the way through to the hose off the tank that should hang under the bike near the battery box.

Second issue is a possible leak in the carb boots or the choke mechanism.

once you eliminated (or fixed) those, then you can start to mess with the screws and other things.

Do one thing at a time and observe what happens before trying something new.

Same problem i had!

Believe it or not, I cleaned the ignition switch puck under the key (That fixed the all of a sudden dying at the worst possible times problem. Like dead sticking a landing.) Cleaning all of the ground (grinding them clean with dremel) straps from battery and ignition coils. Now I have no shutting off nor ANY backfires. I did the marbling and ear shave. Air mix is now at 2 1/4 turns out.

If the pop just started today I would do some other things first. 1. Drain both carb bowls, maybe there is water in there?

2. Check air filter and all hoses

I would clean the carb before changing the settings on it.
