I have a 2002 Harley Davidson Sportster 1200 with cycle-shack slip-ons, and last year took it to the drag strip one day with some friends, and found the joy that is the "blue race fuel", which not only smells really nice, but also seemed to give my bike some real extra torque. I believe i filled up with an octane between 105 and 110 (and laughed at the kid putting 130 into his mom's civic). For how fuel efficient my bike is, i think this year i would like to just buy a drum of race fuel to keep on hand, to run my bike on most of the time.

Is it safe to feed my harley a diet of 110 octane blue race fuel? Is this fuel legal for public road use? Where can i get a drum of the fuel? I live in northern iowa, area code 50613. How long would it stay good, if i just filled 5-gallon jugs at the drag strip to keep in my garage?

What about AvGas? It's low-lead, and i have access to it (father has airplane) but i hear it melts valves on cars. Anyone used it for a prolonged time?
Oh and for those who are curious, my best run in the quarter was 13.6 seconds at 98mph. I had put on a different handlebar, that pulled the cables too tight, only letting my clutch engage 95% so instead of wheelies (which it eagerly will do), i could feel the clutch slip significantly. So i think i could have done 13.0 easily, after i had the shop reset my clutch cable settings internally (it was past the limit of what could be adjusted at the handlebar).
Actually i have plenty of r/c nitro fuel laying around, and it is not anything i would trust putting into anything of value. We put a tank of r/c nitro into a GoPed when we were in high school, and boy that thing ran like a raped ape, but after that it never really, um, ran quite right, ever again. I would be afraid of all the extra oil in the fuel gunking up the engine (the stuff is only 25% nitromethane, the rest is basically castor oil).
It runs like it's on choke when i use 89 ethanol (only when i'm on reserve and nowhere near a decent station) so usually i put 91-93 premium in there. The time i put race fuel in, the thing ran really great it seemed, and also smelled really nice. I think the longer burning perhaps gives more torque at lower rpm's, although i could be speaking out my butt here. If i could get a drum of 110 to know i'd be using it, i'd get the bike re-timed and re-jetted to that specific fuel. Thinner head gaskets for raised compression might be good too (or what would you advice for engine mods to use this fuel? maybe 00 limit on parts/labor)
