I have a co-worker that uses nothing but Aviation fuel in his 2005 fatboy,he also uses it in his 1974 chevy nova SS with a 427. His exhaust pipes on his bike are pure white inside .....he doesn't put many miles on either one but I don't think I would run straight AV fuel in my bike or car....would you? I might mix some in now and again with gas though. You can sure smell it.....lol. He says it won't hurt a thing....I don't know about that.
