Quick breif answer. If you have O2 senors and the 110 is leaded, yes. The fuel will damage the sensors. And as you will read, on stock compression engines, race gas makes less power than lower octane fuels due to the slow burn rates.

gas station by me has cam2 race fuel.
100 octane and 110 octane.
$9.50 and 9.75 a gallon
but they both have lead. i dont think leaded fuel
is gonna go over too well with the engine and o2 sensors.
may even mess up the injectors.

Even if it's unleaded, it's a waste of time and money. A stock compression motor (SE kit or not) won't benefit from it.
Edit: Just noticed that you also have high-compression pistons, etc. In that case, if it's unleaded, give it a try. You may also have to advance timing to get full benefit.

the lower the octane you can use without detonation (ping) the more power you make.
no motor requires a higher octane till you get to around 12-12.5:1 compression ratios and higher.

with all the heat related bitching I read in this forum, I think everyone should try and convert their bikes to alky, E-85. Alky motors run waycooler, downside is the water attraction.

This is 100% correct. If you dont need all that octane your just burning cash and killing power in your engine. You would need a very hot rodded engine to be able to preform on 110

The other downsides are tha you use twice as much alky as you would gas, plus the fuel systems would have to be cleaned a lot or flushed after every use. Plus it has a lower boiling point so then you would have more chance of vaporlock in the fuel system. For an aircooled engine pure gas is the best fuel
