Seeking chain advice

[scotty]

Greetings all,

I'd like to get a chain for the A10 work in progress.

Gbox sprocket has 20 teeth
Rear wheel sprocket has 42 teeth on a full width hub cast iron hub

What dimension/size should I ask for and how many links total  ????

Should any decent modern motorcycle shop stock the right chain ?

Any body on the forum have a recommended brand/type?

Thanks in advance

cheers

Scotty

This information is contained in Roy Bacons excellent [oh yes it is] book a7 a10 restoration.

I will look it up for you over the weekend.

Reynolds chain is the best.

I've been hearing rumours for years that Reynolds chain is only been making industrial strength stuff these days so should be avoided? Any comments? Unless it only applies to us downunder.

In the UK you cannot go wrong with these people, always seen at auto jumbles and classic bike events.They are very knowlegable.        http://www.sprocketsunlimited.com/Index.html

Hi Scotty
From my 1961 BSA Instruction Manual  for G.F and S.R it states the following:

Gear Box  Sprocket 19t
Rear Sprocket  43t
Chain size and pitches  5/8'' x 3/8''  - 97

I guess with your 20t Gear Box Sprocket you will 98/99, can alway remove a link if to long.

Hope this helps
Nick

Anyone knows of a any O-ring chain that would fit, or are they all too large?

Thanks

I don't think Renolds chain is so good these days.
