Hi there. I got a 2006 gsxr 750 with 13,000 miles today. It has an aftermarket straight pipe style exhaust system on it and a power commander as well as a power commander ignition module. I am getting an f1 c46 exhaust valve code. Previous owner claimed this wasn’t an issue but I want to make sure there’s nothing I need to do to fix this. If there is please fill me in. Thanks guys!
