I read in some internet blurb that Meteor Minor engines changed spark plug type after engine number 7027.



For that and previous engines, they took a Champion L7 later L82C, or a NGK B6HS



Engine number 7028 and onwards took a Champion N5 or N5C or Now Gone Kaput (NGK) B6ES.



Also I understand that usually, the engine and frame numbers match for original bike but mine don't. Of course, engines do get changed if they go bang, but here is the odd thing. I have the original R.F. 60 logbook, as the first tax license issued is for 15th Aug 1959, and the vehicle details have frame as 7777 and engine as 6229?



It also says that the vehicle was first registered 15th Aug 1959, so it seems it came with mis matching numbers? Did this sort of thing happen occasionally?



So... I go to check Kevin's secrets and find these...






Headstock, it says 'B' with 7 - 59 under it. Could that mean "Born July 1959" as it was registered Aug 1959? Then there is a raised bit that says 4759, with a triangle underneath. Is this the frame number a part number or something else please?







This is stamped on the front of the engine...





And this on the gearbox.


Are these the engine numbers?



P.S. I don't have the instruction manual yet, so cant look up where the number should be.

Kevin reveals all!




Refering to the 1959 meteor Minor restoration blog (found with google search) I now know where the numbers are!




6229 seems to be the frame...





and this would be the engine then!



At least it ties up with the Logbook! YAY!

Scaly, most Redditch Enfields DON'T have matching numbers especially after 1956 when the same frame was used for a wide variety of models. The Twins had the gearbox number that was originally fitted stamped on the front of the engine as well as it's own Albion number on the box top case. This seems to have been because the Twin engines (but not the Bullets which don't have this number repeated,) were built in a different Factory in Bradford on Avon and then shipped up to Redditch. I recently discovered that this Factory, called Greenland Mills, was later used to build Marcos Cars. But that's another story...

REgards, Mark

And 4759 is the casting number of the headstock, you'd be amazed (maybe not,) at how many Enfields that went to America have this number listed on their Titles (Logbooks,) as the frame number!

REgards, Markk

Difference is plug reach Early 7/16-1/2"

Later ones are long reach 3/4"

No need to say what could happen!!!!

Well done Yorkie, I remembered that after I'd posted!

REgards, Mark

My logbook is wrong, it is frame that is 6229 and engine that is 7777



so the B6ES longer plugs are correct form this (later) engine!



Logbook had it reversed and I thought the engine was 6229, which would have had the shorter earlier plugs!



The instruction book arrived and has been scanned, see scaley's junk link in post above

FYI. The transition from Short to Long Reach plugs started in Nov 1957 with the Indian Trailblazer, and depending on the bike model was completed across all of the Twins by May 1958.
