| Hi,
I moved a 2008 KP from Virginia to Canada. My Bike has a VFC ?III and Vic Swept pipes. I?m getting a lot of backfiring when letting off on the throttle and/or down shifting. Real backfires ? not pops. This seems to happen more when the engine is warm and not when it is cold. I?ve also had it die on me twice while slowing down to stop or rolling to avoid a pothole. Could my VFC require readjustment because of the change in air temp ? Now running too lean? Should I disconnect the battery to reset any adaptive settings in computer?
I checked my spark plugs and they look fine. I also unhooked my O2 sensors with no change. Should I try bumping up the VFC settings?
Guess I?ll have to install an IAV at some point? Exhaust gaskets?
I don't know how the bike ran in Virginia.
Thanks! |

seattle, wa | Don't waste any money on a IAV. Just turn up the gas on the VFC, the green and the yellow modes are what you want to adjust. Move them all the way up to the right and see if it is still popping. |

Jasper, MO | Your O2 sensors should be unplugged when using a VFCIII. If they are not, the bike's ECU and the VFCIII will be fighting each other and you'll not be able to set it correctly.
The Swept pipes are prone to popping.
