On my GV 250 the expansion bottle is directly connected to the radiator.

Good tip as I had several overflows as air bubbled up.

B&L - do most scooters have these issues?  I never had these kind of problems with motorcycles that I worked on.

The bottle is directly connected? You mean with a hose right? The hose leading to the overflow only spits coolant when the system is pressurized past the pressure rating of the radiator cap. This is not a mural problem, but it's kinda hard to burp all the air out.

Yes with a hose between the radiator bottle and the radiator.  "directly connected" was not the right choice of words.
