Great to follow this one, really nice bike. I mentioned before that I bought a red H1 new in 1970, well they weren't built and finished as well as this one. I see you have the same traffic congestion that we have here, too!! :lol:

Your bike looks fantastic Sir! I had a problem with the little drain screws leaking on the S1C I restored. I changed the little gaskets twice(both times with NOS gaskets)and they still leaked, especially when I cinched it down to take back to the owner, it wasn't pretty. I drained the oil for the third time, installed yet another set of NOS little black rubber thingys and used blue lock-tight on the drain screws and now they don't leak. I think I may have over-tightened the first three sets and distorted them some so I didn't tighten the last ones much at all.


Sorry for all your troubles, but that's somewhat comforting to read. Appreciate your tip regarding Lock-Tite. Will also investigate surface around the holes, where the gasket is meant to settle.
Thank You Sir :)

Thanks Baz and Rod :)
Regarding the traffic congestion: Pics were taken at around 09:30 in the morning. Sometimes after the morning rush-hour.
Actually, quite a few danish people have settled in Sweden, but continues to work in Denmark due to higher salary, and lower taxes in Sweden.

Getting closer and closer: Front brake now adjusted, and lever feels quite firm. Lotsa good hints regarding how to adjust this brake here:

Thanks Guys :clap:

Today, I just made a loose fit for the exhausts, to get an idea of the looks:

and finally, oil pump and lines needs to be primed.
And new oil needs to filled in forks + new drain screws .... and ??

Lots of work and other thing during this week, and next weekend are fully booked with non-Kawa related social things :silent:

Kawasaki didn't even prime the pump or lines. start her up , hold the pump cam full on and watch the oil bump through the lines.

really :shock:
Not sure I got the nerve. New liniers, pistons etc. etc. Cost me $$$
During the time I "watch the oil bumping through the lines" exactly what is lubricating the internals :D ???

I could run on pre-mix, though :eh:

Every 2 stroke that came out of Kawasaki. I do it also. Roller bearings need almost no oil when not under load. Up to you....

It was Ascension Day yesterday = off work. Took the day off today, Friday + 2 days during weekend = lotsa time to get all the last small details in place, and get the bike started. It least that was what I thought!'

With 2 new drain screws + gaskets, the front forks has stopped leaking oil. This time, I inspected the holes carefully, and I did apply some LockTite to the screws before finally securing them with a gentle blow from an impact driver. No leaks :clap:

A small amount of oil was filled into tank, and I noticed, how the oil flowed through the main tube, and no leaks anwhere. But when I was to tighten the biggest of the 4 banjo bolts to the pump, the thread just snapped all of a sudden :banghead :banghead
I'm always very aware of not overtighten, and I try not to grip a spanner at the far end, thus minimizing the torque arm. And my alu washers were brand new.
Kind of a bummer :(


So I had to drain tank and main pipe again:

This is how the banjo bolt looked like, when I got it out:

Guess there some good advise to be had here: http://kawi2strokes.com/forum/viewtopic.php?f=14&t=2357

When I removed the pump, I actually noticed that the 3 smaller threads for the lines to the main bearings, had already been Heli-coiled, but not the big one.

So it's time to get myself at Heli-coil set. Never to late to learn some new tricks :)

Pump is off bike now, and examined. There should be lots of metal around the 6mm hole, so it should be too difficult to repair.
The biggest challenge will most likely be to avoid small metal fragments to get into pump, when drilling and cutting new thread. Will have to clean it very carefully, OR to do a complete strip down, before starting the repair.

An original Heli-coil set now ordered. Expect it to arrive sometime next week. Orig Heli-Coil does not come cheap, but I like, that I can dial the number to a specialist company, and get all the advise I need from a guy who speaks my language. That has a cost too.
Another nice touch, which I havn't seen with some of the cheaper brands available here, is that for every thread size (this particular one is 6 MM x 1.0) the Heli-Coil comes with 3 lenghts: 1 x diam., 1.5 x diam. and 2 x diam.

Stay tuned ...

Pump is fixed thanks to this nice set:

and so is Oil- pump, with the Heli-coil repair clearly visible.
