I broke a carburetor heater when disconnecting its cable, its head popped out (the thread remains in the carburetor body).
In the official store I can find it for 50€ each (a LOT) and I wonder if some other Yamaha (or other brand) share the same part under another reference number.
For my Mikuni BDS28 the references are:
Carburetors 1 and 4: 4EB-83790-00
Carburetors 2 and 3: 3AB-83790-00
