I dug into it this afternoon and know jackdoodly about them so...where the jackshaft goes through from drivers to passengers side (?) Theres a tube that in my life looks like a breather or a vacume line but is it an oil line for the jack shaft housing? See attached photo .There was no line attached or found. Iam installing a kill switch tether and noticed this little gizmo on the drivers side top panel (?) What is it? See attached photo. Also I was wondering if there is a air filter enclosed in the hood ? And if so (should be right!) Does it get serviced? I have a ton of questions but I'll just ask one more. Can a dealer service fuel injectors like a car shop does and at 1400 miles should a guy do it. Never really messed with a two stroke. Just car engines. The openings of throttle bodies are dirty in my experience. Just a thorough run through before I venture out. Oh and there is some light surface rust on and around the weights on the primary clutch? Iam not used to these parts but wonder if they should come apart and be cleaned.oh and should a guy replace the exhaust doughnuts while hes in there? And why is there fluid in the bottom of my muffler ? Didnt smell it so dont know what it is lol.Thanks sorry for all the new guy questions .
