yep with 927 its the best
to bad im out again and need to do some glass work before i can ride anymore
You'd have to check with the blender or the makers web site and look at the blend. If it's oxygenated they will list it and it's benefits
I run ERC 110 leaded but also mix it with premium depending on my timing curve and riding type for the occasion. Compression set at 215 but blowing 200 now, max timing between 28 and 34
The Aviation fuel has the light molecule base and race is a heavy molecule base. Weight of fuel is a concern in aviation

If its oxygenated you will need to jet up for the extra oxygen but 2 strokes like the lead in the gas.

It is not so much about "making more hp" as it is not detonating when you have higher compression. So if you are running less then 190 compression you would be better off running straight 93 octane.

? So what if I were running only 170 psi and 38 degrees of advance with a dry pipe? Compression isn't only component, that mindset might get you some new pistons. Quality of pump gas can also tend to be questionable.
My compression tester says 225 in each hole but im not buyin it so I just run 110 leaded for peace of mind. Do I need it? Probably not i could probably get by with 93 but it smells good and puts my brain at ease and for as little as I go through I dont mind paying 7.19 a gallon for that peace of mind

Good point, I was assuming stock timing.

The lead in the fuel slows the burn rate of the fuel. This is why in high compression application it is needed to prevent detonation that will lead to engine failure. Higher octane fuel does not = more HP it does resist detonation due to the lead or other addatives.

the higher the octane, the slower the fuel burns. lead is a lubricant and cushion for unhardened valves and valve seats used on old engines before they figured out that lead was poison.
