I gave my '88 Banshee to a guy that replaced my swingarm. When I got it back, the excess radiator fluid "tank" was hanging from the back, and there was a hose on the right hand side of the bike (looking from the back to the front), that was dangling out. It comes right out of the right side cover, is about 5 inches long, but then goes into a "T" value which goes to nowhere.
So, here is where it gets tough... I replaced the throttle cable (it was frayed) BEFORE determining if the hose meant anything. After replacing the cable, I couldn't get it started (before I gave it to this guy, though, it would fire after the first kick or so). So, now I don't know if the problem is the missing hose (which I have no idea where it goes) OR if the hose isn't really a necessity, but the throttle cable replacement requires adjustments, etc.
HELP.
