gas and methanol dont mix, methanol will make a make run cooler then gas but theres some draw backs....methanol burns twice to three times faster then gas does and also attracts water like crazy, in order to run it you have to have your carb set up for it and perge your bike after ever run, itll rust ur bearings crank and eat away at seals if not perged, if ur trail riding and not a stict drag racer then forget about it, it'll add 10-12 percent in hp but burn twice as fast i can go through a 5 gallon can (meth) in my drag banshee in a day easy.
