I installed K&N filter on my 700 and my gas milage went from 4mil/lit 3 mil/lit 25% less.
There is anyone who know how to change the carburator in order to get better gas milage. My filter is clean with just a bit of oil and I drive in sea level.

Thanks

I bet your running lean and loosing power causing you to give it more throtle to maintain performance. Try jetting up your main jet, should help.
