what octane?
I don't know about your owners manual, but on page 84 of mine, it specs 92 OCTANE OR HIGHER! Around here, 91 pump gas is all that is available, so I add enough Klotz Octane Booster to get it to 93, for a little extra margin.
Your EX is air cooled (maybe sometimes paryer cooled), and air cooled engines run hotter than water cooled. Therefore, you are more prone to detonation, hence you need a higher octane, even though your compression isn't at all outrageous.

Thats funny, I've never seen any production ATV from the big 4 require anything more than 91 octane and thats only on some two stroke and high perfromance 4 strokes. I understand the concerns about air cooling, but I wouldn't think it would require race gas on a stock bike just because its a hot day. If you're running that hot all of the time there's mostl likely a problem.
