I did this and got rid of all the pop except a little bit around 1600 RPM. I'm going to play around with the numbers at that RPM range today and see if that completely gets it gone.

I had the same issue with decel pop since April when I did my stage 1. Couple of weeks ago when I was at Laconia I was checking out the vendors and DynoJet was there. I mentioned the problem and they said pull the bike in, we can fix that for you. I pulled in, they hooked up my PC-V to their laptop, and 10 min later I was riding out minus the decel pop. They said they added a small amount of fuel at the zero throttle setting through most of the RPM ranges.

How do you know what RPM you are getting the popping at if you do not have a tach?

Interesting discussion and cure, I thought decel popping was a result of too much fuel burning in the pipes???

What's popping is the perfect combination of fuel and air. Adding fuel upsets the balance.
