I run 85 to 87 in my Bashan WILL that has a 9.0:1 compression ratio...

And here is what the Emissions plate reads on this bike... it should be noted (again and again...) that it has the generalization of what "Octane" number to use... testing of "Octane" numbers is different depending on where you are in the world...

Where our bikes are made (over in China), they like to use RON (Research Octane Number) as their "Octane" testing and numbers... in North America, we will see it as AKI (Anti-Knock Index) as the "Octane" testing and numbers...

85 AKI is about the same as 90 RON... and unless you slapped a high compression piston in, or your bike is pinging under load (trust me... it shouldn't with only a 8.7:1 compression ratio)... you are doing your bike and wallet no favors by using anything higher then regular fuel
