It does, but can you quantify the difference? For instance in terms of the volume settings on your stereo? Or any other familiar comparison ( you can speak to each other standing next to my T140 when it's running, but you'ld really have to shout next to the TSS. Any help is muchappreciated - sorry to be a nuisance.

Ok, I'm with the program now :y2:

Unfortunately fitting a header system with balance pipe to the TSS will still have you shouting next to it. The difference in loudness is small, however the "beat" with the non balance headers is far more distinct.

To make any large difference to the loudness, different mufflers will need to be fitted.

What mufflers (photo if possible) are currently fitted to your TSS?

Not a nuisance Mike, thats what these forums are all about, sharing experiances,knowledge and information (IMO).

Show us your bike though.. Please

Cheers

Silencers (mufflers) are standard Triumph pattern " long cigars" with pretty standard internals - bought from Armours iñ Bournemouth UK. I have swapped these between the TSS and the T140E and there is no appreciable difference in sound level. I'll try to attach a picture, but I haven' t done this before, so please bear with me. Your help, guidance, and cameraderie via the forum is much appreciated.

Re: 1983 Triumph T140W 750 TSS; 8 valves & electric start! - GrandPaul

Very cool. Was that machine ever exported to the US? It must fly! At 1st glance it has a BSA looking motor (ish) w/ a Trident like tank. Is it stock? My T 140 D I added an oilcooler, knocked out half the baffles in the exhaust but aside from that and the tires all stock. I hear they are making the original Avon R Runners again. I had a pair of the new tread, didnt like em. Anyhow neat machine! Is it electronic ignition? neg ground etc?
 
I bought the bike three years ago with receipts for engine work by Dave Nourish, the rest of the bike is standard UK 1982 model TSS i.e.T140E. The seat is an electric start base with a king&queen squab and cover. I have recently also replaced the standard rear grab handle with the small rack, which was an option on that years Bonneville. I have also removed the zener pack and rectifier and replaced this with a solid state charge control pack.
The ignition is a Lucas standard fitment, and the battery is a brand new sealed one (I've not tried the electric starter as it usually only takes a kick or two).

Thanks for the photo Mike. Your TSS looks in top condition. The cigar mufflers must have made quite a difference to the noise factor. Do you know whether your TSS came out standard with the non balance pipe headers? Is it fitted with the Amal Mk 2 carburettors ?

They are a really nice bike to ride !

Hi Tom,

112 TSS Bonnevilles were exported to the US late 1982 to early 1983. Unconfirmed figure of 383 were produced in total. The US model was slightly different to the UK model. Californian pollution laws required the use of Bing carburettors to meet emission standards. Different mufflers, paint job and no fork gaiters were the other differences. If you browse back through this thread you will find photos of the US model.

The standard T140 produced 47 hp, whereas the TSS (T140W) with its better breathing 8 valve head and higher compression boosted power by 20% to 58 hp.

The addition of an oil cooler to your Bonneville is a great idea. Do you have any photos we can have a look at?

Very nice:y45:


Mike from what iv'e learned in my 14 month ownership of a TSS, (a lot through this forum) is that there is a lot of myths around the bike but pretty its much its a late model T140 with an undeveloped engine (head really) that with a bit of work can be made into a reliable and very usable bike. The fact the your engine has had work done by Dave Nourish, indicates it probably had most of its bugs sorted. Your are one of an elite few TSS owners and a very lucky man ( apart from living in a country with cr*p weather:y2: ( I'm from Scotland originally so im allowed to say that)

Now i reckon there is 7 or 8 TSS's accounted for on this forum, so we only have to find the other 470 odd..... so spread the word our aim is to change the forum name from "Triumph Talk" to "TSS Talk":y15:


Please keep the pics and the posts coming.

Cheers

The ignition is a Lucas standard fitment, and the battery is a brand new sealed one (I've not tried the electric starter as it usually only takes a kick or two).

Very fortunate to have Dave Nourish rebuild the motor. He is THE EXERT with the 8 valve engine. You will have a very reliable and oil tight engine for years to come.
Your other mods are on the button. The grab rail / rack would be a handy addition. Can not bring myself to drilling the required hole in the rear mud guard to fit the rack.SAD If I really needed a rack, I could always purchase a second rear mudguard.

I also prefer to kick start my TSS. Starts really easily, usually first kick. Replaced the sprag starter clutch a while ago as it had collapsed the fine activating levers and would only freewheel. The replacement is a simpler design without the small levers and appears to be more robust. Big thing with the electric start, is to have a strong battery as the higher compression of the TSS will cause it to kick back and this will damage the sprag clutch or worse, split the clutch housing / intermediate cam shaft timing gear and cause all sorts of havoc.

If possible, could you post more photos.

Hey Mike (Original),

How's the assembly going?

Too wet to go riding on the TSS today, so am busy polishing for the show next weekend. :y54:

When I bought the bike it had Norton-pattern peashooters on, and was REALLY LOUD (in my opinion the exhaust should NEVER be so noisy that you can't hear the top end rattling - as they always seem to!!) and was painted in a sort of two tone dark grey. Unfortunately the owner had filled it with petrol (brimmed the tank!) and left it in the sun - so it had a sort of random crackle pattern with (un)attractive yellow chromate primer showing through - no street cred left whatsoever!!
First job was to check it over, take it back to black and gold (sprayed with cans and pin-stripe tape applied in my garage) and change those silencers.
Carburettors are Amal Mk2s - same as my T140E, and the bike is a much sweeter bike to ride than my T140Vs, especially in traffic. Tyres are Continental Conti Blitz (never heard of them!!) and tyre-shine had been used, no, not on the tyre wall but across the WHOLE tyre! A little light safety sanding in order there before any road use. I'm not sure if it's the cast wheels, but it feels a lot more 'planted' in corners than the T140E.
My info. gives 434 total TSS production, can't remember which book - I'll look it out if required. The dimensions of the main bearings in the 1980's on T140's were changed and are actually the same part number as those quoted for the TSS, but I remember reading somewhere that there are other bottom end (i.e. crankshaft based) differences between the two.
I get most of my bits from TMS in Nottingham (UK) - one of the blokes there was in the dealership when they were selling TSSs, and he remembers quite a bit of what went on - the press bike was prepared in the race shop for instance, and a lot of the troubles were dowm to poor assembly or variable quality in parts production.
Regards - sun's out, get the washing out, do the kitchen floor, sort out the bees, maybe go for a ride if the Sunday drivers are still asleep - well, there's always Mugello on the TV.
Happy riding/polishing/dreaming. Stay safe
Mike (the other one)
 
I havent seen a nicer set of lungs since.... well anyhow, I disagree I would say that looks great. I did a pair RED and polished alum up top. I found a .22 cal gun cleaning kit or better yet a .25 pistol cleaning brush set works wonders for detailing these old machines. Spent many many hours w/ the semichrome.... The bike together looks like a stock job I have a pic of the 69 rat w/ the red jugs if anyone is interested.69.jpg
 
Nice. I want a seat like that one.

Seat looks really comfy for rider and pillion.

Thanks for the TSS info. Martin from TMS helped me out a lot for parts with my bike. Really good bloke TUP
Any info you dig up about the TSS will be greatly appreciated.

Cheers
