Are you talking about the decompression plug on the front of the motor?

I had the upper timing plug come out when I was riding. Oil was everywhere. Soaked my boots. My friend saw it. If I was out riding along I'm sure I could of seized it up.

I just tighten mine after every ride. They are sometimes a little loose. Ever since I got the works connection anodized plugs they havent budged. Dont know if thats coincidence or if they are designed to not loosen.

The little plug on top of the crank case on the clutch side.
