Yeah, Spooge. I don't know why, it just called that. It's unburnt oil from your oil/gasoline fuel mixture. Spot-on jetting will minimize it, but probably won't eliminate it. Maybe another brand of 2-stroke oil will help. When we ran 2-strokes I used Yamalube and jetted until I was blue in the face. That got rid of most of it. It will build up in your silencer and cause you to repack more often. Your suspension control depends on the flow of oil in the shock and forks. When the shock or fork compresses, oil is forced through a series of restrictive devices, one of which an externally adjustable screw. Clickers! These are found at either end of your fork or shock. They are called clickers because the have a detent that makes a click every 1/4 turn or so. The click helps you keep track of where the screw is set, generally recorded as number of clicks out from completely screwed in. The more clicks out, the softer the damping (ride). Less clicks out, firmer ride. I'm not sure about which gas resevoir you're talking about, I assume the one on the shock?
