Suzuki Boulevard + V&H Straightshots Backfire?

Question

I have a 2006 Suzuki Boulevard C50 and after 2,000 miles I put on V&H straightshots and my mileage is up to 8,000. I went out for a ride on Sunday, ended up riding through several showers, left the bike in the garage Monday, and Tuesday decided to take it for a ride. Once out on the road, my bike began to backfire frequently and loudly whenever I would decelerate. I am used to my pipes backfiring, but they were now backfiring more frequently and it sounded like I was doing a driveby everytime I let off the gas. I originally thought it was the air filter, but I inspected it and it was dry and clean. Any ideas?

Answer 1

more than likely you have an exhaust leek I had the same problem with a 2003 1500LC I put the same pipes on. Would recommend getting new gaskets and checking for leeks wear the pips slip together and are clamped.

Answer 2

Did you put NEW exhaust gaskets in you bike. ( they are copper rings that will crush when you install your new pipes) If you did not there is a very high chance you have a leak there.

The reason a bike will back fire is because it is to lean ( to much air in the system)

Somehow raw air is getting in to the system and missing up your fuel to air ratio. That is why you have a back fire. I would love to give you more info if you need it.
