Hi, Are the heads of the bolts holding the stays to the mudguard domed or flat. 
On a 1960 '99. The ones on there at the moment look like replacements, they are black with raised writing.
Cheers.

What are original tyre sizes for te Norton Es2 1951 ?

I've just picked up a 67 Cafe Racer. It has been sitting for 5 years, and I'm looking for someone in the Northants/MK area who could take on the project of getting it serviced, cleaned up, and running well.

Hello. My resto cum recommissioning of the 650ss is progressing. Next on the radar will be the cycle parts. You have been warned!

The subject of my enquiry this time is the front brake cable as it passes the front mudguard.

Hello All, 
I have acquired a 650SS that has been in storage for up to a decade. 
I decided to pull the motor and disassemble it to check it out and clean the sludge trap. 

Wanted P11, N15CS or G15CS gearbox shell for my P11 project. Consider complete gearbox for rebuild. Richard

Slimline petrol tanks are secured to the top of the frame by 2 shouldered bolts that screw into captive (cage) nuts, clipped into brackets welded onto the base of the tank.

Lots of discussion on this in the past but I was wondering if anyone has the latest information on this.

Can anyone tell me what the thread form the two attachment screws are on the battery box cover? The threads are in poor condition and putting thread tape on them isn't doing it for me any more.

I'm trying to remove the valves from the head. One exhaust valve came off OK the other won't.
