Compression Test has gone well!

[xxthegonzxx]

Hi All,

I finally finished my compression test on my bike and all is well. A few questions though:

My spark plugs are black and dirty I'm thinking I might need some new ones. I'm also stumped as to what this random nozzle is. It wasn't attached to anything at all. Please take a look at the pictures and let me know if you have any thoughts.

Plugs look OK to me. If you spend a lot of time idling, they'll naturally be blacker. Take the bike out for a hard ride over ten miles or so and pull the plugs and I bet they look a lot different.

Nozzle isn't a nozzle. It's your timing chain tensioner.
