Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Thanks to Charlie Mullendore of Antietam Classic Cycle for contributing this recommendation. In Charlie's own words and photos:
I always wondered why Guzzi didn't put a fitting on the clutch arm so that the pivot could be kept greased without disassembly. Decided I'd add one to the arm of my 1969 V700. Simple job, drill 11⁄64 inch, tap 5 mm-0.8 mm, apply a little threadlocker to the fitting and screw it in. Done.
