Backfiring
OK...so the bike is backfiring sometimes when I pull the clutch and am changing gears. This usually only happens between 1-2nd and 2nd-3rd. This just started a few days ago after I did the 30,000 mile service. The only thing different is that I put in new spark plugs (the old ones looked perfect), cleaned the air filter and I re-wrapped the baffles with fiberglass (the old stuff had all but blown out). This has never happened before. So, what could be going on here? I thought maybe I created too much backpressure with the clean filter and newly-packed baffles. Is that possible?
Other info:
This is on a 2004 Road King Custom EFI. Stage I. Wild Pigs pipes. I've had all of this stuff installed for over 25,000 miles.
Thanks for any input/suggestions...

RE: Backfiring
That is decel popping and it is likely caused from one of three places. An exhaust leak, an intake leak or bad air/fuel mixture. Since it juststarted showing up, I would start with the exhaust. Make sure you seat the mufflers using a high-temp silicone and then snug the clamps up nice and tight.
