Throttle cover hold-down screw (Tommaselli Super Pratic B)
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
The little screw that secures the cover on the Tommaselli Super Pratic B throttle is 3 mm wide × 0.6 mm thread pitch × 3 mm long. The usual thread pitch for 3 mm wide screws is 0.5 mm, making this screw extremely difficult to source. Check with long time dealers to see if they have any in stock.
