Hey guys,

I installed my Bassani Radial Sweepers along with my DK Customs Cyclone high flow 587 air cleaner and used my Vance and Hines FP3 Fuel Pak to map. However, I had to use the Vance and Hines Big Radius map then auto tune after some riding (as suggested by Vance and Hines themselves). However, the past few days when i start the bike, it is has a good idle, but if i give it any throttle, is sounds like it wants to stall. I have a clean A/c Cover, so I was able to look at the throttle body and noticed that when the bike is cold and I open the throttle right after start up that there seems to be too much fuel or something because there was a few fire ***** in the throttle body when any air got in.

Any idea what this could be from? Do you think that map is too far off? Should I remove the auto tune data and start from scratch mapping the ecu?

Also, there seems to be more backfiring and decal popping now the more I ride it.

 

Sounds like its throwing the timing off. First I would check for leaks from the exhaust. Then I would try it with the V&H short shots map. It should be close, but its just a guess on my part. I would do it one step at a time, so that I could narrow down the cause of the problem.
