I just picked up a 1991 Kawasaki 650 SX ski. It appears totally stock, and when i did a compression test it showed exactly 180 psi on both cylinders. So I know its a strong motor, but were the heads shaved? The heads appear stock, it says Kawasaki. The guy I bought it from was playing with the case drain on it, but at the time I didnt know what it was because im totally new to stand ups. Is it closed when it is pushed down? I dont really trust the oil injection system, I prefer to premix. What is the best way to block it off? And what oil do most of you run? Ill probably just mix supertech at 32:1, but I love how klotz smells, if you have smelled it, you know. Also, what would be a good carb to run on this motor? The small single carb on it right now is holding it back for shure. Are these skis hard to jet? I am used to 2 stroke race bikes and sleds, which can require jetting changes for 20-30 degrees F or a couple thousand feet elevation change. Will it be hard to jet for maybe a pipe and air cleaner? For those of you that help answer my questions, thanks much.
