Motorcycle Repair: race gas v. pump gas, race fuels, r racing

Question
I noticed in some of youre answers you talk about gasoline going bad and then varnishing carbs and such.To my understanding premium race fuels like vp cannot and will not varnish. Is this a fact?and if so why?. Thank You.

Answer
race gas is unnecessary unless u r racing. u can add STP or something similar to stop any varnish and keep fuel system clean.  race gas runs to hot for daily driving causeing uneeded wear. it's non-varnishing effect is caused by it's octane levels and purity.
