I've put V&amp\\;H slash cut 2 to 1 on my bike with SE heavy breather, SE racetuner and had it Dyno'd.&nbsp\\; It pops on Decell.&nbsp\\; People on here have stated in the past that is a problem.&nbsp\\; I've also heard that is normal.&nbsp\\; They are loud and sound great(popping and all).&nbsp\\; But I don't want to hurt anything either.&nbsp\\; What's up?

 

mine does it too, from what I understand the Xied will fix it. mine where supposed to be here today but it was coming via snail mail

 

Do a search on decel popping. This is probably the most talked about topic beside fingerless gloves.

 

I have basically the same set up as You.
I love the noise on decel. It reminds Me
of My old Chevy!&nbsp\\;If it is the same popping
that a lot of guys are complaining about then
I am OK with it! But thats just Me!!

 

A lot of the popping problems are found to be because the closed throttle position was not established for the race tuner.

 

my bike has a very slight poping on decell and i have been running it that way for ever. i checked my plugs and they cannot be burning any better. my bike runs great no hesitation i twist it it goes so what ever you heard it depends .check your plugs they should tell you the story if they are burning properly do not do any thing. here is a link to some pictures light tan to gray is where you should be.
