AJS Model 18CS Bitsa identification
Posted: Sun Jan 06, 2019 7:55 pm
Hello to all,
Although I have owned a couple of AJS for a few years, I am just getting around to sorting them out and a novice to the marque. I am hoping that somebody out there can tell me about my bike.
It looks like a Model 18CS, but the engine and frame numbers have been messed about with making it impossible for the dating team from the club to identify it, so I was hoping that the keen eyed amongst you can help me out.
The bike is clearly a bitsa, cobbled together from what ever parts were available.
I have done some research online and asked a few local enthusiasts what parts it could have been made up from, but I am stumped when it comes to the frame. It is obviously a heavy weight frame, but the sub frame is unusual as it has a bracket low down on the near side, just above the rear foot rest bracket (see attachment). I would appreciate it if somebody could tell me what this is for and which bike it came from.
There are some other obvious anomalies, the rear mudguard bracket is too long and the there have been some strengthening plates crudely welded in front of the jampot mounts.
To give you all the information that I have, I believe the engine is as the V5 states, a 500cc, but I won't know for sure until I take a look inside. The V5 states that it is a 1951 model, but the true year is anyone's guess.
I believe that the forks are from a 1947/8 model as they have fill holes as appose to drain holes. This would tie in with the gear gear box as that is a 1948. Apart from the rims being changed to alloy and 18 inch on the back, that is as far as I have got.
I would appreciate any guidance so that I can confidently order parts in the future.
Thanks in advance.
