Carb Jet Question

[cableguy]

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

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.

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!!!
