Replcement engine
« on: 04 March, 2017, 07:52:04 »
Hi

I have just purchased a A65T with matching 1967 numbers, on inspection the engine cases are post 1969.
The bike is from the USA and I have the title which states it was sold in 69.
Any comments

Are you saying that you bought the bike on the basis that the engine and frame number matched but you have now found that the engine number is different and relates to post-1969? Or are you saying the numbers still match but there is some feature you can see on the engine cases which makes them post-1969?

Either way, if you contact the club's National Secretary and tell him what the frame number and engine number is, he'll be able to tell you when it left the factory and in what form (hopefully, as an A65T).

Arthur.
I believe you mean the dating officer, not the secretary, I would not like to see our secretary  bogged down with dating also ::)

It's not a Dating Certificate I was recommending which, of course, only the Dating Officer can provide. However, a forum member previously posted that he was able to get the despatch information for his bike from the General Secretary relatively quickly which is what I was suggesting this member try.

Does the engine number end with a "Y"?

Some A65LA and A65TA (1967) engines are "1970". But they dont have the normal month and year dating letters you would expect from 1969 on  engine numbers.

See the USA Service Bulletin below.

It is also worth going to BSAOC website, under "machine dating", then "engine and frame number introduction" where here is information which may assist. Basically some 1967 machines were not sold in that season and were refurbished and sold in 1969 and 1970 season.
