Thanks for the tip. I did install a pair of Smartpartz quiet baffles in the Jardines. It helped a lot with the excessive noise and reduced the decel popping a good deal as well. I'll try 20226 and see how it does.
Tripp,
I've had the tune you recommended installed for a bit, and the Rocket runs beautifully with it. Prior to the new tune it would surge, hesitate, had a lot of decel popping, and even the occasional backfire through the intake. Now it idles smoothly, pulls strong when on the throttle, cruises perfectly, and only a slight burble during decel. Thanks a lot for the tune. I'm really happy with the way the bike runs now.
