engine numbers a little confused :) 13344xx

Hi everyone been offered a 69 fastback,


*edit*

has anyone got a fastback in the 13344xx range?

curious if yours is points in the timing side case on the r/h or not also if theres a P after the engine number




engine number is 1334 XX (other numbers)

registered 03/09/69

its never had a colour change and is green but the engine number puts it in the s range did the bikes come as fastback in that range of engine numbers to? did the S come in green?

also the engine position seemed a little different to me seen a bit of variation in the position on a few of them but seen about 8 with the full number on the flat on this engine number range but not the 203ms bit on the curve

the 20m3s/ is on the curve part under the first engine stud on the barrels and the number part



Cheers

Tom

No, not all of them would have been 'S' types, other models would also be included that range of serial numbers.

Re: engine numbers a little confused

Thanks mate

seen a few later serials on the 69s with the number where it is on this one but not the 20m3s bit all the stamps look norton an of the year blown up mind so maybe its just on the verge of them moving it round to the side or someone used an old case or something as teh 20m3s bit is a bit more round towards the right than some of the others

big help fingers crossed i get her lil rough round the edges but seems a great bike

Re: engine numbers a little confused

Does look a little odd , BUT - if ' the New Lad ' was put on stamping , and the tea whistle went , he dropped the hammer on his toes ,
or He Started monday and the Supervisor gave him odd directions as he had a hangover , then bawled him out at Smoko for being a
little twerp , even though he had been inadequately instructed , you might get something like that .
It takes a big beefy chap with a good swing to number them deep . a weedy school leaver at his first job wouldnt have the practised swing .

Or Maybe just the bloke who did it had a hangover . :? TRIUMPH Race motors are often stamped on a slope ( or slide ) which makes them look highly dubious .
Where actually in the 50s theyre some of the rarer and more unknown of the best of the crop . This is general on Triumph Pre Units , in the competition models .

Can you get a good square-on close-up shot of the area immediately after the 20M3S/ ?

Re: engine numbers a little confused

Hi Mate,

here's the close up mate




Cheers,

Tom

Re: engine numbers a little confused

Thanks, but it's still hard to tell if the area has been tampered with or not.

Re: engine numbers a little confused



132031 APR 69 I have no reason not to believe it. It agrees with others I've known. 1334xx would have been after mine and probably in the realm of the S, but then if it stayed in UK probably not. Roy Bacon lists 133668 as Fastback with camshaft points. My engine number is all together in that area, I'll get a pic tomorrow if you like.

Re: engine numbers a little confused

Thanks Dog, thats interesting to know mate if there's others out there like this, seen a few where all the number is on the side but not split up like her

just a shame that the numbers not like yours would be a easy decision then

the logbook reckons its been green since new so probably a fastback uk since registered

Thanks for the pictures massive help especially the vin interesting to see the stamping

Re: engine numbers a little confused

Just a curious question here.
Why do some people blur or black out the VIN when talking about their bikes.
Afraid they may be stolen bikes?
Don't want anyone to know where they live?
What's the reason for that?
Just curious
Mine is 308*** for the 74' and the 73' is 304***

Re: engine numbers a little confused

somebody copuld assume its a ' clean ' number for their country , for ' cloneing ' .

Re: engine numbers a little confused

oops! I've been cloned!

Re: engine numbers a little confused

did it as they were the pics sent to me not mine yet hopefully soon though, be interesting if any more crop up like this

seen a few where its all round to the right but none split like her

Re: engine numbers a little confused

has anyone got a fastback in the 13344xx range?

curious if yours is points in the timing side case on the r/h or not also if theres a P after the engine number

That's one too many digits.

If an engine has the 20M3S prefix, then it should have the points housing in the timing cover.

Fastbacks with the points in a housing behind the cylinder block should be 20M3. According to Roy Bacon's "Norton Twin Restoration" book, 133668 is supposed to have been the first camshaft points (20M3S) Fastback, however, 13344x has the 20M3S prefix.

'P' denotes a Plumstead(AMC)-built engine.

Thanks mate yup I 13344x it is just trying to work out if its had a replacement engine or not and been restamped was ding steve wilsons book last night and saw that it mentioned the later engine number on the fastback as being the one with the points in the timing cover as apparently they used the points ones on the S and the older engines in the fastback, having said that maybe they ran out earlier

know my 650ss is a P but was thinking if 13344x is meant to have the P its not there, ordered a factory records check reealy cant wait for it to come through should answer a lot of questions

Either he listed to the right , or had a right leg two inches shorter .

Nice touch . ( same bike ) .

" Q. i'm not a mechanic, would you fix the misfiring to guarantee the bike if i bought it on the auction? Apr-30-14

A: At this point in my life, I'm pushing the broom and cleaning up after myself, ready to turn out the shop lights for the day. These British bikes are part of what made us mechanics in those days, as they were always in a state of coming undone with every mile rolled. Cable, clutch and carb adjustments made on the fly as a day heated and cooled. Slimey cases were only the sorry truth leaking out. Hole a piston on the hottest day and go see your machinest the next day with a cold six-pack also under your arm as tithe and bribery. Funny, collecting these bikes today has become a richer man's hobby and a credit card needs a staggering limit to pay others royally who once aced VoTech classes and excel at when to use a hammer or profanity to fix the reoccurring problems. The hours of wrenching are needed to appreciate the afternoons of riding. These bikes have a sexy exhaust note to arouse almost anyone, but the wiser buy may be a used Hinkley Bonneville with only a few miles on it and no need to start a second career with grease always under your nails. It's the journey, not the ride (bike). Find better things to do with your time. It's another beautiful day out there. In good humor, don't waste it! '"
