Tec 202 Camshaft - Street Twin 900

A breakdown of the cost is as follows ;-

Cam £360
Post £6
Shim x3 £15
Alternator gasket £9

No need to change oil and filter for this job as none lost and mine was only 1 month old of low miles.

 

Yes, agreed on the shocks and a Hagon/YSS upgrade maybe down the line (also agreed on the FOX though they do look premium - which one would expect at that price!) .
I should have added above that your spoked look great and interesting to hear (as many others testify too) that no problems being tubed. So the T100 in black fit without issue? I had heard that but you the first I've seen to show. Currently £825 from Triumph https://triumphdirect.co.uk/products/black-wheels-a9648040 (but I'd get some £ back from selling the casts). Triumph World have a set for the T120s on a great deal (been on ages) but I guessing these won't fit the ST -

I do like the aesthetics of my Crafton Atelier seat and prefer to the Motone offering but your custom seat also looks great and as if it might offer up a bit of added rider height (?) whilst also retaining the raised rear for pillion which I did like about the stock (as did my wife!).
You've got me thinking about those spoked T100s anyway!

 

Great that you made your own special tools and saved a fortune. The camshaft timing plate alone is a frightening £138 (World of Triumph).

 

Well done on the body weight loss as it all adds up, I could do with doing similar myself but it ain't happening

 

Does your shocks have a damping adjuster at the bottom?
My shocks are very similar but all black and were already on the bike when I purchased it, however they don't have the collar yours has.
Assuming it's a damping adjuster, is that for compression or rebound damping?

 

Just a quick observation the TEC cam doesn't fit the older air cooled engines such as those fitted on the 2012 Thruxton 900. I'd hate for you or anyone else to waste their money.

I will also say (as I have observed in threads elsewhere) that my experience of the TEC cam is much the same as @Eldon's, especially the sense that the gearing is better, I'd been thinking about messing about with rear sprockets to see if that would stop me looking for a 6th gear, but now the gearing feels just right.

 

Is that the Motone Side panel? And does it cover the upper frame rails better, or is it that your seat sides wrap lower down the frame? Like you, I'm not happy with the exposed loom and upper frame rail under the standard saddle on my Street Cup.

 

Yes I agree, previously I was always running 5th gear on A roads, however, now I can find myself hovering in 4th ready for an opportunity to overtake, or happily sat in 4th corner to corner on a B road.

 

Me too and yet my fuel consumption remains at least as good as it was before.

 

Of all the bikes I've worked on, which is quite a few, these twin Triumphs are a piece of p155.
The space, access etc. are to be admired. Take for example Triumphs own triples, access is tight in places ( see pic below). I needed to helicoil a street triple 675 head for the cam chain tensioner - Engine out would have been the dealer answer no doubt, or head off, with significant costs, yet with a few self created special tools, then it can be done in a couple of hours.

Street twin tips.
Use special pliers to remove petrol quick disconnect when removing the tank...... don't ask, easily cocked up and Triumph want £77 for the fuel pipe, no separate clips
Easily sorted for £4 if you know where to look.

Take your time and be careful with the injector plug disconnection, this is small, fiddly and awkward.
Watch any chain tensioner reset clips intently.
Use the two specialist tools and camchain timing is easy.
Ensure you have good incremental feeler gauges for valve clearance checks.


Look how tight this chopped down drill bit is to the frame? ( ST675R)

Yes the T100 wheels are a straight swop. They were worth around £600 when I had them fitted and as Bill Smith's had no use for the original ST mag wheels they gave them to me. I sold them on this forum for around £350 I think.
No, the T120 wheels aren't a straight swop but that is a very good price.

 

Yes it is a damping adjuster but I can't remember what it adjusts . To be honest these shock are so basic I would be surprised if the adjuster made any difference. I'm not one for messing around with suspension settings. I recently noticed that TEC don't list them anymore and heard it was because the original supplier has gone out of business (or somesuch).

 

Yup, they are Motone side panels. I don't like the Street Twin logo and thought about respraying the original panels. Then I saw a pair on the Square Deals site, with 3 horizontal slots. They were inexpensive but lasted about half a dozen 'removals' before 2 of the fitting posts snapped off. After a couple of failed attempts to repair them they went in the bin. It was around this point I discovered Motone and the rest is history.
They don't cover any more of the frame than the originals, it's the seat that does that. I wanted the stepped look of the original but with the tuck'n'roll style. Aftermarket bench seats, of all makes, look like they're floating on top of the frame, which looks wrong to me. I wanted the seat to hug the frame.

 

Thought I'd show the Motone ribbed engine cover now fitted and you can just see the Motone footpeg which replaced the TEC pegs.

 

This is how the ST looks today (headlight bezel soon to be changed). Note the battered bash plate. There are two of the 3 Hondas it shares the garage with.

 

Spam, mods might as well delete.

 

Many thanks for your words of wisdom.

 

In addition to @RevPaul comment, I'm not sure @Baza if this, or similar, is actually an upgrade i.e. fast road cam, from a normal scenario.
I'm wondering if TEC somehow got wind of the originally intended Street Twin cam and so rightly mark this up as a "derestricted cam" rather than a " performance cam".
Maybe your youngests Thruxton in effect, prior to further emission controls and accounts/marketing fiddling, may already be on par and so little, if anything, to gain.
Bear in mind the Thruxton has been Triumphs flagship nostalgia model for quite a few years now.

I don't see it anywhere marketed as a performance cam, do you, or anyone else?

In comparison, the 1200 offering, is marketed as a performance upgrade.

 

A cam change was part of the facelift/upgrade by Triumph for the 2019 onwards Street Scrambler/Street Twin giving the bike an extra 9-10bhp. TEC say their cam just brings the older bikes up to 2019> spec.

 

I wouldn’t be surprised if this is the case. When I’ve ridden the machine I’ve never found it wanting. But it could really do with a sixth gear. When we went to Wales last year the fuel consumption was not good. We are off again next week but he’s taking his new machine this time. Thanks for your observations.
