Tank - I'll assume then you have the correct map installed and you have been altering it along the way. First thing I would do is to flash it back to the original state and begin again. Should take minimal changes down low in the afr table to get good results...go ahead and use the same table for both front/rear cylinders. Just increase the 30% and below blocks a few steps each time and test. Let us know how it fares. I will also make the assumption that you have checked for exhaust leaks.

Since this is a very slow back and forth on the forum I will just check back from time to time...got a motor to tear down this morning.

 

Have you tried adding fuel at the zero throttle position? If not try adding 4.

 

I have short shots and took the baffles out and hack sawed about 1/3 of the way through the side of the baffle at 1/3 and 2/3 the way from the end on opposite sides and bent the sides in about 35-40 degrees so that when the exhaust comes from the motor it hits the bends and deflects towards the side ...it made them a good amount quieter but mostly helped to stop the back firing...just enough back pressure to help but not so much as to slow the bike down..just make sure you bend it the right direction, you want the exhaust gases to deflect off the bend, if you do it the wrong way the exhaust gases will be caught and reversed back up the pipe...

 

How will I know if I've gone to rich with any particular setting? The oil already smells kinda like gas, probably just me being paranoid. I really want to work this problem out just for personal gratification. I'm gonna replace the head pipes seals just to be safe, I've checked the flange nuts several times.

 

Mrfikser, I've tried the lollipop mod but it didn't help. If I can't tune it out I may have to start hacking on the baffles. thanks

 

Have you tried contacting the Power Commander manufacturer tech line? I went with the Fuel Pak on my wife's 883 SuperLow with V&H Short Shots and the only issue I have is a little rich.

 

Dang, I like summer and lookin' at the girls w/short shorts!!

 

I tried email but got no reply. I guess I will have to call

 

Would it be possible for me to stop the decel popping by leaning out the 0 throttle position position column? All the popping I get is at 0 throttle when I'm coming to a stop or gearing down.

 

you need to add fuel to the 0 throttle position to help get rid of the popping
