Had my local shop install Hardchrome pipes (2 3/4) with a jet kit.had a lot of backfiring on deceleration and between shifts. Took it back for adjustments and they got about 70 per cent of the back firing out. Took it back again and am presently waiting to get it back. Is this a normal process or am I helping to train their mechanic? The bike is an 07 model with 2500 miles on it and no other modifications.
