Called a guy up today that had a 1985 250r that was kinda rough. We were talking about the trike and he said "I don't have any gas or oil" so I told him "well go get some gas and I'll bring the oil" He said "what do you mix it at?" I said "I prefer 40:1, what type of oil have you been running" He says "5W30." I could make a whole page about our conversation....but you get the just of it. IT PAYS TO ASK QUESTIONS lol
