Howdy!

This is my first post here at this awesome forum!!
I hope this is the correct place to create the thread.

I have a XT660X -06 with no mods and I am interested in knowing if just by replacing the standard cans will affect the air/fuel ratio, if so how much? Will I need Kev's fuel mod?

I have a very slight surge problem and nothing that bothers me so I would mostly be buying this mod because of the cans, which is why I am asking this.

Any advice and suggestions will be greatly appreciated!

no, the end can should not change the A/F ratio

Okay good to know
Thanks for your answer!
