The only reason to add top lube as Bigger was talking about with the methanol is to lube the carb, floats and top end since the methanol is corrosive. Methanol is great in the warmer weather but it sucks as the temp cools down. The quad will run very cold and is hell to start. I run methanol because I dont run a fan and its very forgiving while jetting and its cheaper if you have to run high octane fuel. Thank you and now I will shut up.
