I recently purchased an 87 Kawi JS550 standup. The Clymers manual doesnt list a lubrication for the crank besides the grease when putting it together. By searching forums I have learned that it runs on just the oil in the fuel mix. I have a really hard time believing this. As it is would be a major issue if i broke the thing trying, maybe someone else can comfirm this. My local Kawi dealers are also perplexed and dont want to reccomend anything due to liability. When i bought it it had water in the cylinders. I took the engine out and the head off. And dumped nothing out of the crank via the flywheel cover. should i just rebuild the whole thing or what. i really dont want to.
