Put a set of V&H slip-ons on my 1100 about a year ago, sounds great but now it pops at idle & when you deaccelerate. bypassed the AIS system & can't find any leaks in the exhaust. I think I might be a little lean on the fuel-air mix. Buddy of mine suggested putting a jet kit in it which seems logical. Whay say you o great gurus of the Star Bike Nation?
