I done a stage 1 on my bike and I'm getting a little decel popping in low gear when I let off the throttle.It also stalled a couple times in low gear. I noticed when I shut my bike off I here air coming from my A/C and was wondering if that is normal.
I put new header gaskets in but didn't get new clamps or the crossover gasket.

My set-up is Fuelmoto ceramic headpipe, 4" slash up mufflers, FM A/C, and Dyno Vision with custom map. It was put on a 2011 SG with the 103.

 

Call Jamie, let him know about your decel popping, he'll probably send you a new map that eases off the decel enleanment. Assuming you have no exhaust leaks...

 

PLease let me know how this turns out for you. I'm looking at doing the exact same set-up only with American Custom exhaust. I'm going to be ordering the Power Vision and Fuel Moto A/C when I get back to the states. Thanks
