I hated those bikes when they were new because they weren't "traditional" style Triumphs.

Now is a different story...they are "unique" to me today and the rarity of them makes them more desirable!

Thanks Guys,

It's been a fun project. Missus wants her credit card back to go shopping now that the jobs done. A lot of damage to the card....will take a couple of months for it to come good.

Will post some photos of the internals soon.

Inside the beast.

As I found the insides. Overall very good condition. Replaced all bearings, seals, O rings, gaskets and cleaned out the crankshaft oil tube.

Bent exhaust push rod tube was the cause of the major oil leak it had when I bought it.

All good in this area. Never been apart.

Found new stainless steel valves in the head when I stripped it. It appeared they had only been in a very short time. Suggest previous owner had the unleaded petrol conversion done and when assembling it, dropped the push rod tube, bent the O ring lip, put it together and when he ran the engine, threw his arms up in horror when the oil pored out.

Coming together.

Note the push rod tubes are splayed, as the rockers are rotated 180 degress compared to a 4 valve, to provide a very shallow valve angle.

Head on.

RockerShaft.jpg


Polished rocker shaft to assist lubrication of top end. IMO the lubrication to the rockers using airated scavenge oil, bled off from the return is marginal.

Head going on with Cooper rings held in place with Locktite 518 gasket silicone.

That engine looks very clean and well taken care of. Nice photos! Thanks for posting them.

Hello again guys,

Have managed to get the appropriate number plate for the TSS. Could not believe my good fortune when I went on line to the transport department and found this plate available. Shouldn't be surprised I suppose, as there are very few of this model around. Still waiting for the Australian compliance plate before I can register it for the road.

One of my vintage bike friends has one of these bikes, but it's in need of a complete restoration. We keep hearing about it, but it's either lack of money, lack of ambition (or both) that's keeping it off the road. I think he has had it for 20 years.
I don't think I have ever seen one in person.
It's a great looker.

Many thanks for your comments of the TSS. As I didn't require any machining work, the paint job was the only thing I needed to out source. I had a professional classic bike restorer do the job. He used standard Triumph paint codes, however his use of the highest quality two pack and his amazing skills makes the difference. The tank had a crease on the right hand side under the badge and he actually panel beated it out with special tools he has developed for the job through the tank filler access. Some tanks he has to cut open along the welded seams to panel beat. It was by far the most expensive single item of the restoration ($1100.00 for tank and side covers). Worth every cent as it has added real quality to the bike. The other expensive parts were the brake master cylinders. Luckily having the previous owner convert it to unleaded petrol and fitting the stainless valves and hardened seats saved me a packet. The total cost of the restoration including new tyres, materials, special tools, on road costs and insurance was $4580.80. Initial purchase costs including transport from the USA and import duty $10,500.00. The number of hours I spent on it.........countless and enjoyed every moment. Number of bits I dropped on the floor....many, but found every one of them. When the valve spring compressor slipped and the split cotters went flying, I thought I would never find them. A bit of fishing under the work bench with a magnet sorted that. Money wasted due to lack of knowledge. $135.00 for a Morgo Rotary Pump that does not fit into the space in the timing cover of the electric start models........Dam! No alternative but to buy a bike to fit it to. Major lesson learnt. The cost of the wife's new car to keep her focus off my spending......far greater than the bike and restoration costs and worth every cent. Now, lets see what I can fit a Morgo Rotary pump to.

I like your attitude. You must have a bike to used that Morgo! TUP. You have a beautiful bike.
