I have a pretty much stock 2003 XB9R. I have a K&N air filter, but have not installed it yet. Would there be any benefit to putting it in? Or would it run worse with it because it would change the air/fuel mixture? Thanks | ||

Putting the air filter in will not cause any issues. There will not be much difference as the stock filter flows pretty good(depending on condition) and the air box on the 03 is pretty restrictive. I would go ahead and slap it in, what else are you going to do with it? | ||

Try it out & post a follow-up on what you think/feel. |
