I have a k6 750 and am having major problem. I noticed today a sludge coming out my radiator and overflow tank. I stopped, let the bike cool off. Took the cap off and put distilled water n it and drove home. It wasn’t smoking and will still start fine. I got home and took both hoses off left side of bike to the water pump. It was sludgy af too. I hosed it out real Gud but I’m scared to try fixing something when I’m not sure what need fixing. It started w cracked stator cover. I patched it and it rode fine for one day til the case got here. Ran fine when I parked it. Got up n went down street and all this happened at once. What is my problem and where do I start to fix it? All inquiries n comments helpful.
