Haven't gotten a pc yet, saving up for pcv, ill check if I have any exhaust leaks and work on removing the entire system with block off plates. I also heard that getting ivans fce would help too
Wouldn't Ivan's FCE make it worse? The fuel cut stops the flow of fuel and Ivan's device is designed to defeat this thus causing more fuel to run through the system. That should equate to more unburnt fuel in the exhaust, thus more popping. UNLESS, you put in the PC and map the excess fuel out.

/ When you suddenly close the throttle, the incoming air is choked off and the closed injector also causes the bike to return to idle on the VERY lean idle circuit . However, momentum of the bike is actually "driving" the engine in a sense, and that engine is still spinning at rpm that needs far more gas than the closed throttle can provide. The engine is still spinning but the incoming fuel rate is very low to NONE until just enough builds up in the combustion chamber to fire.. " pop "
The FCE or a flash will keep the injectors on even on decel ( no fuel cut )
For all I knew, pumping raw fuel into a chamber starved of air would lead to an overly rich mix that would not burn completely and would allow fuel into the hot exhaust system.
Thanks!
I have the ECUnleashed reflash with AIS blocked off and a 2 Bros Slip On, gutted cat etc. I still have the popping on decel. I did however install a P1X tip and it helped a lot.
That doesn't seem logical unless the hoses leaked. You are effectively doing the exact same thing whether you just plug it or use the plates. Like Hellgate said, the popping is revealed by the pipe. My pipe only has 3800miles on it. I had the AIS active at first and it popped pretty bad. Removed and it got better, but still annoying. When I installed the P1X tip, the popping was greatly reduced and is liveable now. I am saving my rat hole money for a Akra or Suono.Did you just block the AIS line at the air box or use block off plates ? Just blocking the hose only reduced my popping. Capping the system at the valve cover got rid of 95% of my popping.
