I'm performing a light tune up on my bike, I purchased a new air filter, new spark plugs and a new fuel filter. Upon removing the number 1 spark plug had some oil on it. Is that something I should be concerned about? The oil wasn't on the electrode part but in the threads part. The plug wasn't swimming in oil but it was noticeable. I have all the plugs gapped and ready to go in tomorow, I stopped at the number one plug because it got dark. Boy, dis the plugs and air filter need to be replaced. After everything is all buttoned up I'm expecting the bike to pull like a beast.

 

Oil in the tube means leaking valve cover gasket.

 

After 16 years of service it's now time to replace it. Weekend project? I think yes.

 

Adjust the valves while youre in there.

 

But not this weekend, its gonna be 80...
