Comments on: Why do I have a loud bang and fire coming from my Harley exhaust after a high rev? http://harleypipes.com/why-do-i-have-a-loud-bang-and-fire-coming-from-my-harley-exhaust-after-a-high-rev.htm Wed, 08 Feb 2012 07:06:38 +0000 http://wordpress.org/?v=2.7.1 hourly 1 By: The Freak Show http://harleypipes.com/why-do-i-have-a-loud-bang-and-fire-coming-from-my-harley-exhaust-after-a-high-rev.htm/comment-page-1#comment-1244 The Freak Show Sun, 20 Sep 2009 00:04:18 +0000 http://harleypipes.com/why-do-i-have-a-loud-bang-and-fire-coming-from-my-harley-exhaust-after-a-high-rev.htm#comment-1244 If you have popping on deceleration after wide open throttle, you can increase the mixture in the zero throttle position cells. I did that to my old Roadking which had a similar problem and it cured it. It was a few years ago, so I don't remember the exact proceedure, but it was really easy. If you go to hdforums.com, you will find the instructions there. I had the PCIII USB and it was a really incredibly nice piece of gear. It's funny that someone ripped on it. I am thinking they probably never had one. It really opened up the possibility of tuning your bike youself, and if you don't like the results, it is extremely easy to just go back to the previous settings you saved ahead of time. One thing to consider is putting the baffels back and see if it cures the problem. I'm not familiar with your specific pipe, but I have never had any luck tuning a bike with a wide open exhaust like that. Good luck man! Plug that PC into a lap-top and see what you can do.

I added a stage one kit to my bike, which included exhaust, K&N filter, Ram Air Box, and Remap the computer. I've noticed that even little changes will effect the bike and results in unwanted behavior. People have changed their pipes and end up with back fires. Even if they are pretty similar to the original. I've heard that adding a fuel management system works only if it has already been remapped correctly. In other words, your bike is thinking that it's still running with the old pipes, but the power commander is trying to compensate. It would be better to get it remapped and then use the power commander. Newer bikes are tricky, since they are fuel injected.
