Bought this bike used and trying to figure out some of the venting. On the clutch side you can see the black vaccum cap and hose clamp. In my Clymers manual it labels that as the exhaust vent. It shows a filter and a hose in the diagram, but doesn't say what the hose goes to. Does the hose just point down, or does it connect to anything? The other question is... on top of the cylinder on the kick starter side there is a vent fitting. It looks like mine is missing and has been since I purchased it. Again it's in the diagrams, but only listed as a union. Per the diagram it looks like it is for a vaccum tube, but again....nothing shows where it goes. Anyone know where it goes to?
