Not much have happend since last post.
Lots of details needs attention now, and I'm compiling it all together trying to get an overview of what's missing .

Being new to triples, i've been reading a lot about petcocks (and hydrolocks). Mounted the petcock on the tank

but realised that I might take it apart again, to ensure that the lever is not pitted http://www.kawi2strokes.com/forum/viewtopic.php?f=14&t=5989
Also bought some special tape for sealing the treads, but I need to check for any leakages tank can be considered finished. More to follow ...

Besides from that, I got the right 10mm nuts for the for bolts fixing engine to frame. And at the same time, I found som nice OEM shims in UK:

so engined is now shimmed, securely tightend to frame, and sprockets were aligned in the same job :)

Ok - I built this ingenious device so I could test if tank and petcock leaked:

Image

Image

Of course it leaked, but not where I expected it to. It leaked around the lever, like if some gasket was missing.
But AFAIK there should be any gasket - right ?
Anyway - after emptying the tank, the petcock went off again :banghead
Will have to work it over again, more on this later...

As I' m still waiting for some parts and a paint-shop, I decided to have a look at the exhausts. They are nice (one of the reasons I bought this particular bike) but not perfect, and I intend to keep them as they are, at least for now and the next couple of summers.

So i started polishing the mufflers - again, not perfect condition, but definately acceptable:

You can get a set of repro pipes from Doremi, but they are out-a-stock for now. Not sure about the quality, but at least theay look nice on the web :lol:

The Exhaust pipe holders (18069-024) were in very good shape. You can get them on Ebay, but these were made looking sharp again, after a bath in my Ultrasonic cleaner. The various muffler clamps are new, though:

Adding some new copper gaskets for the exhaust + some nuts and spring washers, things came to look like this:

Made a second try with the petcock. Still leaking, but not as much as before - what a consolation!

Spritits are low now - time to adminster the euthanasia: Reading the Maintenance Guide :lol:

After a short while, I realised that the fault was all mine: I had placed the big round spring washer between the petcock body and lever instead of btw. lever and the plate which holds the lever in place. The one with text "ON", "RES" and "PRIME" :banghead
Will make a new test tomorrow when there's light outside (winter time here in DK, it gets completely dark outside at 17:15 hours) And I Won't be inside my shop with gasoline pouring out everywhere.

To consolate myself, I ordered some new rubber:
Image

Good ole Dunlop K81. One of the universal cures for bad handling in the 70'ties. Ordered them via web, and they were delivered to my address 2 days later, nice!
Love the looks of these tyres, bringing back good memories
Kinda funny - I still keep some danish reviews of the H1, dating back to 9/69 and 2/70. In the 2/70 issue they actually tried the very same rubber:
4.10-18 Rear and 3.60-19 Front. Slightly wider than the original mounts, but this is the way, if ya want the K81's. Some things hav'nt changed over the years - except for the rubber compound, hopefully.
Looking forward to putting them on the rims...
