I have TT100's for my H2......a lot has changed over the years, including the compound in those tyres. Sumitomo owns the Dunlop Brand, and they are equivalent to a modern sports/touring compound. The GT suffix indicates a softer sports compound as well. I reckon they look great too!

Thanks Rod ;)
At least here in DK, there was'nt a GT choise, I think.
Obviously I hav'nt compared std. to GT compound, but the std. seems pretty soft, when just pressing a nail into it :lol:

Sumitumo ??? - I'd better google that !

Also bought some special tape for sealing the treads, but I need to check for any leakages tank can be considered finished.


The seal is between the end of the petcock tube and the end of the tank nipple, where there is a gasket. The nut just pulls the parts together, but the threads do not need to seal. This allows the petcock to be turned to the desired orientation, and the nut tightened.

Great info Jim, thanks :)

Drove by the paint shop today. The engine- and clutch covers were'nt finished, but he was actually working on it. When I took them off, they all had minor scratches, and the generator /points cover L.H side even had some dents. He's doing a great job, and I'm sure they will look brand new when he's finished.

I have always wanted to able to measure piston TDC exactly, and I also prefer to adjust the iginition setting according to piston position before TDC, rather than fumbling with a clumsy degree wheel.

As I will be doing the ignition timing in a not too distant future, I bought this on Fleaybay:

.. from Poland, I think. Cost me like 7 USD plus 6 dollars in shipment.

It's very well made, solid and with a good finish. The thread is 14 mm, same as for the spark plugs, and it fits nicely.

But I wanted to get rid of the ruler...

.... so I can mount one of my Dial-gauges...

Next step was to drill a 4,2 mm hole, perpendicular to the large tube , and cut a 5mm thread. Then I milled away some of the metal in the top:

Image

Image

In the 5mm thread I fit a little Allen screw, just to prevent the dial gauge from moving.

Image

I had an extra extension tube for the dial-gauge. It needed to be shortened a bit, and I rounded and polished the tip of it, so it won't scratch the top of the pistons.

Finished:
Image
Did a quick try, and it works great. The hole process took me 'bout 40 minutes.

It's a great satisfaction to be able to build your own tools, even though you havn't started from scratch.

More updates during this weekend, so stay tuned ;)

still run my 69 H1 with TT 100 K 81 but next tyres change will fit BT 45, the TT 100 rear does only 4000 kilometers , BT 45 rear on my H2s does 6000 kilometers+ and the BT 45 slide beter than the TT 100 :mrgreen:

Nice dial gauge adaptor! I have a small one that can actually go on without removing the tank...a bit tricky with the H2..

Interesting !
Your remark about sliding better is not only fun. In a contemporary road test, I read that fitting a tire with almost zero slip, actually puts greater stress on frame and forks.
But as we all know, these were top-drawer quality on a 1969 H1 :lol:

Thanks !

Yeah - your'e right about the size of the thing. Was my concern too. Did think of cutting down the tube, but I did not. Only an issue with the mid cylinder, but we'll see. I still havn' t tried it while tank was mounted.

The TT 100 actually doesn't slide it suddenly lose adherence :shock:
