Wanted to add a quick note on the install of the AIS
removal kit on an '08 R*...
The kit I purchased (LA choppers version) had four items in it: 2 block-off flanges, a rubber cap, and a plastic plug.
For the '08 model the only parts it appears you need are the 2 block-off flanges, one for each cylinder. NEITHER of the two plastic parts appear to apply to the '08. If anyone thinks I'm wrong on this I'd appreciate a head's up so I can do a proper install.
In my experience the removal of the AIS on an '08 immediately resolved a backfiring / popping issue introduced by install of aftermarket pipes (Dooley's) and BAK
