I have tried every thing, even installed V&amp\\;H fuelpac.I can`t get the popping to stop?Anybody have any thoughts on this problem?

 

Put SE exhaust gaskets in and re-tourque everything from the head back.

 

Sounds like an exhaust leak.

 

Ya know just some exhaust systems are prone to have a little decel pop. Use to be the NORM. in the Good Ol Days.

 

Yeah I just learned this first hand, it doesnt take much of a leak to cuase popping.&nbsp\\; My leak turned the chrome yellowish

 

Check the rear exhaust flange thats the one that normally works loose

 

If you had a SE race tuner, you could increase the decel enleanment, which is what I did.&nbsp\\; Decel popping is the burning of unburned fuel that continues into your exhaust pipe.&nbsp\\; If it is a small exhaust leak contributing to the burning of that fuel, you're still dumping unburned fuel into the exhaust. The exhaust leak is just contributing enough oxygen for the fuel to ignite.

 

+1 thoght that was part o the rumble/grumble cool sound.

 

I too have the FuelPak and slight popping on decel at lower RPM's\\; had it since Day 1 of the install. Other than that, bike runs fairly cool and is efficient on fuel. Overall, I can't complain about the FP performance.
