C12 or Sunoco 110 leaded mixed with oil. Might not work as well for your bike though...
I'll have to try the ethanol equalizer product in my street bike ('99 SV650). If the bike sits for any length of time with regular ethanol-positive gas, the carbs get really nasty and the bike runs poorly, if at all.
I found some local sources for ethanol-negative fuel here:

Doesn't look like there are any options near NJMP, but there are a few near Summit Pt.
In general, if your bike doesn't need the detonation/knock prevention that race fuel offers, save your $ and just use regular pump gas at the track and then fill up with the ethanol-free stuff when the bike is going to sit around.
