Starter - BMW starters will not fit
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Thanks to Kevin Kelly for sending me this information.
Found the problem and thought you might want to know.
Bought this starter off E-bay about 8 years ago and was listed as an Eldo starter. I checked it to be sure it worked and stuck it away. Found out after doing some careful measuring it is for I think an Airhead BMW, but is very close to being the same and not noticeable just looking at it...
Ohh well live and learn.
