[QUOTE="markjenn, post: 190917, member: 42"] And there's a lot more to octane requirements that simple compression ratio: size of cylinders, water- vs. air-cooling, carbs vs. FI, camshaft timing, ambient conditions. I don't know about the current one, but my old R6 had 13:1 compression and run just peachy on the Yamha-specified 86. This is a tired subject and just like there are people who believe fuel magnets really work, there are folks who are going to believe their stock engines run better on higher-than-specified octane. But if the engine isn't pinging, more octane does absolutely nothing. - Mark [/QUOTE]
