I am buying a 250r that runs on alcohol and i need to know what all i'm going to have to do. I know you have to purge it after riding or what not. I have been hearing about talk about top end lube or something of that nature. I just want to know what i have to do to to run it.... like put in it before i ride besides oil. Also heard something about having to change the oil after every ride.lol. i know i typed a lot but i just wanna know what i'm getting into. Any help is appreciated. Thanks, Josh.
