Well Today I told my brother to drain out my gas because it was pretty old and he was like yea yea.An hour later he calls me saying he didnt drain it out because he had no container so he just let it idle.Well it ofcourse overheated and spit out all the coolant by the front of the bike and now I dont know which coolant is best for my bike.Or can I just use any 50/50 or any coolant.Please help me because im a pretty big noob with this stuf.
