Hi Peter,

I'm not sure if it's possible to tell AJS/Matchless or 250/35 from the frame number.
The engine number tells you which size it is. Info below...

Well I got an AJS 1960 with license, but wanted to know just for the record when it was an ajs or matchless

Can buy an engine from a friend and theres number 1960/8 .... in
Does that mean a 350(model 8) from 1960..

60/8 would mean it is a 1960 model 8 350 AJS engine.

59 would be engine built in 1959 model year
G2 would mean 250cc
877... would be the engine number

Thanks, but got 877 case and that must be 58...
I also thought 250 and 350 ar nearly the same.
There s a lot compltely different.
Cant use a lot of things 1 on 1
I thought it was easier to look for parts if it fits, but this gonna be a hell of a job.....
But first Im gonna be busy cleaning those 17" DUNLOP rims :D
