I have installed Vance & Hines pipes, k&n high flow, and a power commander. The bike backfires bad when I decelerate. I've had it dyno tuned and it still will not run right. Any advice or experience with this problem? Thanks in advance for trying to help.

Welcome to the forums....

Which power commander did you get?

You should be able to contact dynojet, tell em what you've got, and they can get you a map to the PC...... You have the hard part outta the way, lol, now it's just fine tuning the PC.

 

Thepower commanderis a usb Kaw .The shophas several maps tried with no positive results. The bike has been on the dyno 2 different times. They can't map it right. The bike runs fast, but the backfiring is terrible. Thanks BigRig18Wheeler for your responce and welcome to the BB. I'm just out of ideas and don't want this shop to do anymore work. They just can't get it right. I was hoping someone else had this problem. I will contact dynojet and see what they say.

 

No prob.....

Call dynojet. They are good people. Tell em what you got, what's been done, and what it's doing, and they will fix ya up. Good peoples everytime I had to deal with them.

Let us know what happens.
