That's a very reaslistic price. I don't need another one, I DON"T need another one! :y14:
The frame / engine number has it 15 units newer than mine. Looks totally original....nice.

MMMM.. not so sure about the price? I'd pay that for yours, a bike that's well sorted and condition known. this one is fresh of the boat, not complied or registered. Plus you would have to do all the basics,tyres, brake hoses etc. then rego.

IMO only

Need to get on to the new thread, not getting any empathy there...
 
Hello all,
It has been awhle since I have posted anyting.

I recently rolled out my TSS out for ride and when I put the rear brake on, the rear disk pads would not release completely. There was way too much drag. It was difficult to impossible to push the bike until the brake pads released a little. Even when freed up there seems to be too much drag, espeialy compared to the drag from the front dual disks.

The rear brake fluid reservoir was low but not empty; howver the brake fluid looked a bit murky.

Any suggestions or short cuts? Do you think the rear master cylinder is the culprit? Or do you think the calipers are mucked up? I don't look forward to a full blown rebuild on the rear brake; there seems to be too many part buried under the bike, and it is too cold to be laying on my garage floor.

Thanks for any ideas.
 
I would start with a good flush and clean brake fluid and see if that solves the problem.

As carl said, the easiest things first.

A good flush-out and fresh fluid.

Caliper may be sticking at the rear wheel.

Hose could be perishing, becoming a one-way valve.

Last resort is to pull the master cylinder out; may God have mercy on your soul.

Hi Sea Dog, Get the head checked out, They were contracted out to the cheapest bidder and some of them were bad castingings and were pourus.

Hi royrocket. Head all good. Has stainless valves and hardened seats fitted to run on unleaded. Although there is obvious pitting in the casting, nothing is porous. I have fitted helicoils to the spark plug threads and will fit helicoils to all threads in the head and barrels if I strip it down again. Another problem in the head area was the incorrect taper machined in the liner / barrel mating surface and the liners would settle, causing the cooper rings (head gasket rings) to leak. As you say, the castings certainly went to the cheapest bidder. It's a shame, as the design is a marked improvement over the 4 valve engine.
 
Hi Seadog, Norman hide does a mushroom head valves for the T140, Don't know if they fit the tss but they stop the sideways robbing on the valve seats.
Refrence you name are you yo x sailor by chance. I'am an x submariner. Roy

Hi Roy,

Spent 26 years at sea, half of that on square rig sailing ships all over the world and the other half in the merchant navy. After having command for many years, decided to swallow the anchor and am now a marine pilot in Queensland , Australia. Far better for a family life. As a submariner, you would have been in the US Navy I suspect. It would be very interesting plying the oceans below the surface. I'm sure you had your share of adventures. Talking about adventures, the TSS has been one. Great motorcycle now that I've got it breathing properly. Last weekend went on a 170 mile ride with a group of 16 modern Triumphs. The TSS took cruising at 70 - 75 mph in its stride with plenty left for overtaking. Huge grin factor! :y2:
 
Hi Seadog, I was in the Royal Navy, Never being on a square rig would have love to try it though. Tss sopuld piss cruising at 70-75, A good T140 will cruise at 80ish. Bet you had them on the twisty bits though. Roy

Hi Guys,

Back from a two week adventure holiday in New Zealand. TSS fired up easily after the break. Fitted a new oil pressure gauge as the one I fitted at the rebuild failed. All good. Pressure between 60 - 65 psi at idle when cold, which it was when I rebuilt the motor. Will take her out for a run when the weather clears to see how things are when hot and let her rip in the twisty bits.:y2:

DunstallMufflers2.jpg


Just fitted a pair of Dunstall Replica mufflers. Closest match I could get to the originals without going to huge expense and getting some made. Reason I did this, is the originals are impossible to source and mine are in excellent condition. Best preserved in a box as I use the bike a lot. At $AU180 a pair the dunstalls are good value and they sound brilliant. The baffles are removable, which I just had to try.........REALLY loud!! :y2: Baffles back in now so that the revenue collectors don't harass me.
Time for another ride before the rain sets in. :y54:

Hi SD

Santa brought me a pair of those nice mufflers, any tip on fitting?

Mike
