Gas type 87 or 93
This is probably a no-brainer for you guys but...what type of gas do you recommend using for a 2008 sportsman 500 HO...and what is a ballpark estimate on miles you can go on a tank ...I realize riding conditions will impact the number but under normal trailriding conditions 50% hills/50% flat the rest at elevations between 1000-2000ft
Thanks

I'll chime in.
Yes on waste of money and..... There is a potential performance issue as the higher the octane, the slower the burn. I wonder if you would end up with an incomplete burn and pollute more? And without a complimentary advance in spark timing, it makes no difference in power.
Certainly a motor like this has less valve overlap and a higher resulting dynamic compression ratio, but the engineers who built it had a certain octane in mind.
I ran 92 in my XR650L (read: big ole four stroke) with alot of mods and it ran hotter without any noticeable gain in power. I wanted to keep temps down. I switched back.
