I replaced my Scorpion cans with MIG cans after my off and when I went out yesterday I found that there was a ????...ummm....like back firing noise??? when I slowed down
The bike was Dyno'd/KnN (stage1) when the Scorpions were put on ~ do I need to take it to be re done or anything now I have the MIGs on or is it a case of one setting fits all?
Thanks
