got 5500 miles on 2005 vmax with hmf pipes since new. everything else is all stock. have been running great until week ago im getting more of a popping sounds when giving gas and letting off in the right muffler only. changed plugs/still does it. what to do?
 
Make sure your intake boots (all 12) are fastened tight and aren't cracking. THere are 4 vboost boots, 4 from the airbox, and four on the bottom of the carbs that hook to vboost manifold.

Check for exhaust leaks. Make sure headers are tight and check for leaks at mid-pipe and mufflers.

Other possiblities is bad gas in float bowl. Try draining and check for debris and/or water.

Could be stuck coasting enrichener too.

+ 1 to Mark and;

What did the old plugs look like - carbon build up, etc... good idea to post a pic of all 4 if you still have them.

Would be a good idea to run some seafoam threw the fuel tank.
