Popping on Decel, hesitation at WOT   Technical-Bikes

Hey guys! It’s been a very long time since I posted. The bike sat for a couple years while I dealt with other issues. Now it’s riding time again! Here’s the issue:

Drained tank and carbs, put in new plugs and gas and some seafoam. Got er running but she would idle for a long time. I balanced the carbs once I got it warmed up. PMS screws were a 1/4 turn out, Mikuni thumb screws. Running 2-1 exhaust with 150 mains and 22.5 pilots. Pod kits as well. I’ve had this exact set up for 11 years and it’s been fine. Right now I eliminated some popping but only if I have the PMS screws in seated. It still pops on decel and pops and hesitates when I’m really getting after it. 
what am I missing?

Couple of things ... both since its been a couple of years without it running.   1st and easiest would be to check for cracks in the rubber nibbles that you have covering the ports off of each intake.   I would guess you have rubber covers where you hooked up to do a carb synq.   Check them ... bend them a bit ... mine would dry out every couple of years.

2.  Remove carb and check your pilot and main jets.   The pilot has 3 holes to check and main has one.   Run a small wire thru each and use magnifying glass.

i just did mine. it's pretty straight forward. follow the kb and you should be alright. i'd also change the bushings while your in there.

I will check those. Just had the rubber fittings off for the carb sync. One was hella tight and one popped off kinda easy. Maybe I’ll put a new one on there. I’ll end up checking everything like the carb boots and all for leaks. I was able to tighten one bolt on the rear exhaust but only like 1/4 turn if that. I am not looking forward to taking the carbs out, it’s always a pain. 
 

So I’ve had this carb setup since 2009 and it’s run great but I haven’t cleaned the carbs in a while.
