Hello everyone been away for quite some time and about to pick up a tiger cub tomorrow!

Very excited to say the least

It's a 1967 t20m so it's a mountain cub.

A few questions.

Does anyone know what workshop manual parts manual and owners manual goes with this model?

There are several each numbered but I seem to get lost in those details.

Want to join the cubsite forum but it's been less than easy! Any tips or way to reach out to Steve?

Hi Mr.Ferenc


I have two Tiger Cub manuals....both supposedly Workshop manuals.
The oldest one is called Instruction Manual No.6 and applies from engine No. 26276 [but doesn't state if there is a ceiling on the engine numbers it applies to].


The newer reproduction manual [from JR Technical Publications] says Instruction manual No.8 for the T15, T20, T20C and T20S.


The only spare parts manual I have is labelled Replacement Parts Catalogue No.1.


I don't have an owners handbook.
I have found that between these books I have been able to rebuild and maintain my 1962 Cub.
Note that none specifically mention the T20M. I wish I could be of more help, perhaps you could try contacting one of the manual suppliers and see if there is something for your bike?

I now have workshop manual 8 and 7. Both of which don't mentione M or SM models but they might have a lot in common with S and SH?

Anyway I found a parts manual online. Which is parts manual 1 which is the correct one.

I do have an owners manual so I'm set for that and a Haynes but still not specifically for M/SM

I am on the forum and can ask Steve via pm if he has your details.

There are manuals on the site so I will take a look

I recomend the "tiger cub bible" by Mike estall -I have his email as he keeps a register of bikes
I recently bought a DVD called "the triumph oracle" and it seems very good- pdf's of almost every triumph Manual

Greystones in the uk are tiger cub specialists

Hey thanks I wrote to Steve but I may be on his bad side as I didn't read his email in time and we have now miscommunications

Hope that gets resolved as I really want to contribute. In the mean time I will be doing that here.

Could you send me his email I'd love to ask him a question.

DVD sounds awesome.

I'm in the USA so greystones looks awesome but I'd love to get parts closer to home.

I'll be posting soon about more details and maybe even get some official info posted

Hi mr.ferenc, Congratulations on you new Cub!!

I have a '64 Mountain Cub. Was a dirt bike. I started restoring it in 1979. Motor & frame are done. Tin parts was a hold up. Back then no internet. Cub parts were very hard to come by. Now I've retired & hope to get back to it next year?? I've been concentrating on my 1973 Tiger 750 for the last 4 years, plus catching up on deferred home repairs.

It seems the Mountain Cub was originally a USA street legal off road bike. I don't know if it was offered in UK.

Regarding the manuals I ended up getting the Triumph DVD from Kim the CD man Australia. About $70 US with shipping. This DVD has pretty much all the Triumph workshop, parts books, owners manuals, factory service bulletins & more. I strongly recommend it.

The index alone is about 20-30 pages. The index is listed by book so not obvious what content is if your not familiar with all the books. Once you get a handle on all the info there is logic to it, but info is vast. I finally printed the index on paper & then hand wrote notes on index regarding pages I was interested in. That made it simple to locate my books. Basically covers bikes from 40s through '83. I don't recall if later bikes are covered.

I expect you know this, but Mountain Cub had the high compression, high performance SS motor with large Monoblock carb. Mine had a wide ratio transmission so 1st gear was lower than normal. Gave good power in the hills at lower RPM. Bike was surprisingly powerful back in the 70s when I rode it before tear down.

Now with it's high compression I don't know how it will handle California fuel. Maybe you can keep us updated on your progress & how it performs?

I always wanted a Cub since I was 14. At 15 1/2 I tried to buy one at a local Triumph/Honda shop. The owner refused to sell Cubs to teenagers as they were not durable. Ended up with Honda 305 Scrambler. That was a good bike! Anyway, now I have a Cub which someday I can do short rides on. Long rides I'll use the 750.

Your Cub looks very original & seems to have all correct parts. That is huge plus. There seems to be a strong aftermarket for Cub parts these days. It seems they are still used in Speedway racing too. Just like the big bikes, Cubs have styling that is just so beautiful. There are a few cubs in our local club, but nobody seems to actually ride them. Someday I'll change that, hope you do too.

Thanks for the posts everyone!

I have been chipping away at it.

Replaced the oil and fixed all the leaks on the lines and the oil tank.

Cleaned out the gas tank which had a lot of loose metal flakes.

Replaced the petcock

Not much more and it?s started very quickly!

Really interested in that oracle triumph item! Looks awesome and seems really well priced.

Hi All, Here's a cub question. The above, '67 mountain cub has original type frame like my '64. However there is a '67 Bantam Cub with the BSA frame. Oil tank & gas tank look different as well as frame. Did they make a Bantam mountain cub also, or in later years?

Or am I wrong about this frame? I look at pillion peg supports to tell frames apart. Is that correct?

I had friend in high school that had mountain cub orange/white. Square barrel engine. What year would that have been? The square barrel could have been subsequently fitted?? In 1969 it looked new or nearly new. Was always in the shop, but we loved it.

We all had Hondas. Mostly CB or CL 90s. A few Honda 50s. One guy even had a 160 scrambler! The Triumph was so cool compared to a Honda. A 160 or 305 scrambler was close though. And... a Ducati Diana. Now that was the top of the bunch.

I will look it up in the Bible but afaik "no" - they stopped production of the swan necked triumph frame with (in the uk) a nacelle in favour of a bantam frame (having to make an oil tank as bantams didn't have one) .This was 66-68

There was a round bantam cub tank followed by a tank that was a modified bantam one . Afaik all the heads/barrels fit all engines - it went from early round to mid oval to square

http://www.bantamcub.co.uk

They may have used up a stock of cub frames especially for the French army and mountain Cubs ?

Eventually the cub "became" the b25/t25 in 69

The Mountain Cub was probably the best as far as durability is concerned with the roller bearing big-end. The square barrel also probably cooled it by a degree or two! :wink2: Here's a before/after shot of mine that I sold in the late '90s. I sprayed it mist green rather than the grenadier (orange) red.

The roller bearing and square barrels and matching head were on many Cub types, not just the Mountain. Ball bearing mains were from early '62 onwards according to Roy Bacon Triumph Singles. Mine is T20 82XXX mid '62,and has the ball bearing mains and they are OK. The roller bearing setup was supposedly better, but many Cubs with the ball bearing setup did OK.
I personally would avoid earlier plain main bearing models, stick to the ball or roller.

BTW, I'm 6ft/183cm and 90kg and I've ridden mine on 200km round trips on several occasions. I normally ride my bigger bikes but the Cub did it easily, and that was up some pretty steep hills along the way. Tonka tonka tonka at say 40 or 50mph, sometimes getting to 60, but mainly 50, slowing to say 40 up steeper hills, it was a smile inducing novelty tbh.

Hi Nestor,
original t15 lucas al.rectifier
Firstly, welcome to the Forum. :)

In case you are not aware, "original ... rectifier" on your bike was selenium. These were superseded around sixty years ago with silicon diode rectifiers, at least in part because selenium is poisonous when burnt ... :eek:

The rectifier @DAVE M has advised is a cheap, widely-available Chinese type that have been around for over forty years to my certain knowledge. The only change necessary on your bike will be to connect one of the rectifier terminals with a wire - if your bike's electrics are 'positive earth', the rectifier terminal marked with a "+" should be connected to the battery positive terminal.

Hope this helps.

Regards,

Mine was a bit iffy when a mate checked it in 1976. He bunged in a couple of (for the 70's) modern components. You can get a simple rectifier for £5 at autojumbles and it's a little plastic box. Original rectifiers don't need to work

My very first bike was a 1966 Tiger Cub, back in Dublin. CZH332. It was the most beautiful motorcycle I have ever seen and even today I compare every bike to that original work of art. The excitement was mixed up with the Beatles, Stones and all the other sixties music and just growing up! It cost me £65 and I sold it for £70 and bought a 1959 T110. WKO239.
