A tickler! This is the first I'd ever heard of such a thing... I guess it's like the little rubber clowns nose on my lawn mower that I pump a few times to prime the carb?
Oh, and after a bit of googling, it looks like it is the correct body work, just that it is missing the side covers. In most pictures it looks like it's all one piece, but check out this link: http://www.rcycle.com/1974BultacoAlpina250.html
Rich B, you mentioned lighting... is there anywhere I can get a wiring diagram? Without lights, it's just a wire from the stator to the coil, right? Is there anywhere I can find a repair manual? There has to be a PDF one floating around, right? Oh and yeah, I'd be interested in the airbox; let me know.
Anyways, thanks for the help and encouragement so far.
