Ha.. a dirt track around the garden for “test spin”… (:

Had a look at the main beam issue and it was as thought.  Yellow wire with single male bullet from switch disconnected from the headlamp main filament/blue indicator lamp double female connector when I fitted the lamp back into the shell.
Two minute fix involving one screw.

That bullet was the only possible explanation for losing both the blue light and main beam together.

Tested and working fine.  After two weeks laid up, bike started on second kick and quickly settled down into a reliable idle.

Things are afoot in the lounge display case....

Just received the registration document.  It is the old 1977 "R" suffix and is in the taxation class for an historic vehicle...
That means tax and MOT exempt.  Well you have to tax it once a year, but it is free.  Only thing that costs is insurance to ride it on a public road.

Just ordered a black numberplate for it as befits an historic vehicle.  Then its out on the road for a road test as soon as the salt gets washed off the road.

Good news. 

So no inspection requested by DVLA? Could be that your own photos helped with this, so worth noting. 

No inspection needed.  Yes I think the before and after pics worked out, but what was probably the clincher was the covering letter detailing every document and pic, so they could hold them up and know exactly what they were looking for.

Stuff like mentioning original colour, graphics and missing road equipment replaced with the same type and spec as it originally left the factory with in 1977.

Since I had my riding gear on for testing the 175 and the gates to fort knox unlocked, I thought it time to take little yeller out for a spin.
Started her and let her warm up for five minutes just idling before setting out.  She did not want to take throttle and was bogging down.  Four stroking really badly and not wanting more than half throttle.
I thought the carburation was way off.  However it seemed to clear  a little in second.

100 yards further it had cleared completely.  I think it was just fuel that had condensed and pooled in the cold crancases while I was warming it up.

So what do I think of little yeller?

What a peach of a bike.  Lovely motor that pulls strongly, is dead smooth and is an absolute hoot to ride.

After a mile and warmed through I took her up to 45mph and she did it easily, revving out cleanly.
I have no doubt she would easily do 50 - 55mph, but being realistic, 40 to 45 is really the max you would want to be doing.  She sounds very busy at 40mph.  55mph would be at 9 or 10000 rpm.  I have too much mechanical sympathy for that.
The brakes need bedding in, the front in particular is a bit weak,  but apart from that, no problems.  I absolutely love it.

It must be comical viewing though.  I am not exactly a small bloke, ex bodybuilder and that bike is absolutely tiny.  Little more than a kids bike with road gear on it.  A drum sat on a pea springs to mind...

Another one back where it belongs.


The difference in size between the 175 and the 100 is easily seen here.  Both bikes were parked up and photographed in exactly the same place.

Well done mate!

Tinkicker, are you sure?

Pretty sure.  Both front wheels on the floor.  Back wheel raised off the floor by 6" or so, so you can probably knock an inch or two off the 175 handlebar height.
That  77 onwards 100 is a tiny bike.  Far smaller than its previous incarnations.  Its like riding a moped again.  A complete hoot.  I am rather taken with it...

Reminds a lot of a big wheel TY80.

Are you sure the pane on the right side isn't magnifying glass?
