I noticed on the underside of my 650 seat that it says 91 octane or higher. The gas station near me doesn't have Premium, they just have 87, 90, and 110 octane. I'm wondering if 110 octane will do any harm or good for my machine? I have just been going to a farther gas station so far, but just wondering.
Thanks

 

Just use the 90, if you really want to use the 110, go for it. It won't hurt your engine, and don't be fooled by the "high octane+higher HP" all high octane gas does is help with pre-detonation. Your motor has stock compression probably so the 90 should be fine,

 

I meant "high octane= high HP"

 

110 octane will make the engine run hotter,if you have a high compression piston you would need to.

 

I have never heard of a high octane gas cause an engine to "run hotter". Usually is it the other way around. The flash point of a lower octane is lower which ignites easier, hence potentially causing more heat. In otherwords your will most likely see your engine temp hotter with 87 than 110.
