cableguy Posted April 22, 2009 Share #1 Posted April 22, 2009 I have a 96 Royal Star has the four K&N Cone filters on top of the carbs and has vance and hines slip on exhaust. I was thinking about taking the baffels out of the pipes and i was wondering if i had to change the jets in it. Problem is when i decel i have a really annoying popcorn sound in the coming out of the exhuast. Any Ideas Link to comment Share on other sites More sharing options...
pegscraper Posted April 23, 2009 Share #2 Posted April 23, 2009 That popping on decel is the idle mixture being too lean - mixture screws or pilots jets. These early Royal Stars didn't have the AIS, so it won't be that. Four pod filters on the carbs certainly required rejetting. Do you know what sizes of jets are in there? Removing the baffles from your mufflers usually won't require any jetting changes. Link to comment Share on other sites More sharing options...
gator06 Posted April 1, 2010 Share #3 Posted April 1, 2010 I had a 98 RS. Put K&N filters on the carbs, Removed the packing on the baffles in my V&H slip-on's and re-jetted to stage 3. Theirs an article out there covering the procedure. Do a search for the " Big Foot Mod " You will be surprised, no more down shifting to pass!!!
