I recently bought a 2012 VRSCF and it came with the V&H pipes installed. I’ve been noticing a lot of backfire and popping on deceleration especially through 4500RPM down. Saw some older posts here but was wondering if this is due to the aftermarket pipes and if putting on the stock ones (which I have) would solve the issue. The bike has 7000 kms (4350 miles) on it so I wouldn’t think there is something wrong with tuning/fuel (running rich or lean). I’ve had the bike less than 2 months and it did this from day one but seems more frequent and noticeable now. Any suggestion or input would help. Thanks!
