Glasspack mod

[wiplash123]

  I just finished my bike. I used 36" slash cut stacks and Flowtech Purple Hornies. My I/S never looked better and sounds even better then it looks. The power seams to be the same. The only thing I am not sure of is she pops back when I down shift coming to a stop I know all the cars I put glasspacks on did but is that normal on a Valkyrie?

Yep did the glass pack mod years ago and pop on decel, adjust your mixture screw out to 2-1/2 turns, and you did use new copper gaskets at the headpipe, make sure you tighten after hot to specs, they do sound nice.

yep...glass-pack's will pop on deceleration...not backfire...you will get a low rumbling with a low pop every once in awhile just like the cars do...at least all 3 that I have do...
