I tried the search feature but didn’t come up with anything that really helped.

I have an 08 sportsman 800 with several aftermarket items that greatly affect the fuel mileage. I am lucky to get 50 miles to a tank. I was looking at the manual and noticed that the touring edition is a 6 gallon tank where the sportsman is only 4.1. I have never really looked up close at a touring model but I thought the only difference was in the back end to accept the other rider. Can anyone shed some light on the subject as to dropping in a touring tank to get a little more range??

Thank you for any and all help.
