95" Popping on decel.
Just had a 95" installed with the basic sert download.The engine works fine except for a lope at the low rpms may be due to the andrews cams.Also Ive got a decel popping,Im going to have the engine dynoed with the sert when I break the engine in.But in the mean time can I use the deceleration enleanment to lessen the popping?

RE: 95" Popping on decel.
Your decel pop may be because you are running lean, or an exhaust leak. I was experiencing the same thing, nothing too bad though. I had to take the exhaust off to do some work on the bike. I noticed the header bolts seemed to be torqued real light when taking the exhaust off. When I put the pipes back on, and tightened the header bolts, my decel pop was gone. You may want to check your fittings, and make sure the stealer through in new crush gaskets on the headers. they are only good for one shot.

Exactly...I've had this problem twice; first time a leak in my exhaust and this week because the crush gasket wasn't replaced when my bro did the earlier work.

I second (or third) the advice on the header bolts - they need to be tightened with a good torque wrench to around 120 inch pounds (check to be sure of that setting) - it's an area that needs to be retorqued a couple of times as the gaskets get some hours accumulated. They are a little hard to reach - that's probably why the dealers don't do it [8D].
