I'm only asking here because it seems there are people here who might be able to help me. (i know it's a motor cycleracing board but I desprate I don't have a manual yet) I have a 91 kawasaki 550 sx stand up jetski that I had for a long time. I bought it in 2000 rode it for a summer and it has sat since. I have a place to ride it again so I want to rebuild it. Is there a way to crank the motor without the starter? I have a battey and the starter seems to work but the pistons are not moving. I hit the starter for a second but don't want to ruin the motor if it is locked up. I have removed the head and the cylinder walls seem fine. I have sprayed carb cleaner into the cylinders and it seeps though. I do not have a manual yet is there any oil I have to add to the crank? Is there any tips on trying to start an old unused motor? Any tips anyone haswould be appreicated.
