This is probably a silly question, but could someone tell me what the 2 little H59 screws are for that screw into the headstock / headlug of the slimline featherbed frame?
They are highlighted in the attached diagram. The parts manual also refers to them as H59 and 21977. I thought perhaps they are to hold a flyscreen or a nameplate or possibly to enable the head to be lubricated?
Thanks a lot
The De Luxe models had a metal trimming plate around the headstock, held on using these screws. When the De Luxe withered away, some standard bikes in about 1963 gained this fairing also. My 88SS has the plate. It's entirely guesswork, but maybe the works manager found it a convenient way to get rid of bits of metal that would otherwise only have gone to scrap.
I keep it because it arrived with the bike. But it has two drawbacks:
1) it makes it impossible to properly inspect the headstock connections
2) it leaves even less gap than normal to pass cables between the tank and the headstock.
If you wander round a collection of Dommies, you will find a small proportion have this fairing. None of the bikes in the National Museum has it.
My bike is a 1961 Model 50 and it has the sheet metal trim piece on the headstock also.
Doesn't seem to have much or any function at all other than to clean up the headstock appearance.
Thank you David and Michael for your replies. Much appreciated!
