Vstar exhaust and intake mod


New member
I just added a new cobra intake and a freedom performance exhaust system to my 2010 Yamaha Vstar 950. I also have purchased and installed the cobra FI20002 fuel management system. I am having trouble with lots of back fires on deceleration and even between gears. Was wondering if there is much I can do about the issue or if it needs to be taken in and tuned? I am worried i wont be able to get rid of the issue.

Thanks for your help.
