So I spilled a little fluid on/around the right side front spark plug hole. I noticed air bubbles so I figured the spark plug was loose. I pulled the boot and lo' and behold I found the cylinder head water jacket joint. Funny looking round brown thing with a pin in it. I don't know for sure if the air was coming out of that or the spark plug hole. I ordered new plugs and will have them in later today. In all my years, I realized I never even changed plugs on my bike.

Has anyone ever had this air "blow by" from either the spark plug or the joint? Is it possible? Fixes? Ideas?

Thanks in advance.
 
Thank you....Seems it was boiling fluid....:rolleyes:🤦‍♂️🤷‍♂️The drain holes were plugged. I've had three Maxes and have not had to do much service. One crashed and totaled, the other traded away. Feeling kinda dumb...
 
Well, you did the diagnosis yourself, so good on ya, and thanks for the report on the solution.
