Most of the mail order places carry it. All of the motorcylce shops around me stock it. It was invented by a guy that lives in Boynton Beach, FL. About 30 minutes from were I live. We put it in my friends Banshee and it lowered the engine temp 37 degrees. One bottle will be enough.
they sell it in a bottle of a half gallon (im almost sure thats the amount) and you will have a good bit left over after you use it. mine was $16.99 for it but it is very good & will be worth it in the long run with lower engine temps mean longer lasting right? you will want to flush your stock coolant out also with water before you use this & this stuff you just pour in...no water needs to be mixed with it.
