Hello I just bought a 2005 Honda Vtx 1300 r. It has aftermarket pipes but I can’t find what kind they are. It also has a k&n air filter with end cap. Cracking the throttle it gets up and goes fine. But starting out or maintaining speed it will spit and sputter. Also has a lot of backfiring when letting off the throttle. Not sure if dynojet stage 1 or 2 would be best. Anyone’s help would be greatly appreciated..
