getting closer with the '73 H1

I've been working on my '73 Kawasaki H1D 500. One problem with two strokes that have sat too long is that the crank seals dry out with can dry out and cause catastrophic failure.

I found a "donor" motor that I've been getting ready to start. I just ( today ) got a really good deal on a fresh crank for the original motor.

So I "buttoned" everything up to start a rebuild of the original motor. You can see the original motor sitting next to the back tire. Here's what it looks like so far ( with "survivor" tank/paint/tail )



Here's what it looked like originally ( not my bike )



After this motor is done, I'll start on my '74 H1 500

edit

Here's what it looked like after 20 years of storage. I had it in a friend's barn for a while. I traded a couple weekends of roof repair for dry storage. He moved my bikes to a leaky section of the barn. All three triples had rear drums corroded fast.

I like it. looks really good so far, all you need really is to get it running, then worry more about the looks.

btw, would you mind telling me what that rear tire is? I have one just like it on the CB550 I'm getting, and I want to get a few more of them.

Dunlop Gold. I'm pretty sure there still making them as they are very popular for the restoration crowd.

Yes, I'll getting it running perfect before I dump money into paint.

I love it. I had two triples, both Suzuki. In the early 70's my friend George had a maroon-colored H1 and took me for a ride. Lasted about two minutes. The front tire was in the air more than it was on the ground. And speaking of tires, I use Metzeler's Lasertec's on my GS1000. Skinny bias/ply with tubes, but on tight roads I can hang with the sport bikes.

Thanks Mike. Kind of tough to get parts from the dealer so Ebay and a couple of guys from the triple forum keep it going.

There is chromer on Frankfurt Ave in Phila that does excellent work. I've been lucky enough to get nice pieces off ebay and from Jess Freeby for this one.

I've been putting "second best" on the '73 and saving the better pieces for the '74 H1.

If I can find a '73 H2 front fender ( for a decent price), those are polished stainless steel and can be polished with a buffer

That tire I think has been around since 1975. my CB has a set on it that are the originals. yes I'm positive they're original too. bike only has 75xx miles, or somewhere around there.

If all goes well, I should have two "smokers" ready by spring.

Here's what the '74 looked like new ( it's the same colors but this one isn't mine )

Here's what I did yesterday.

I'm pulling apart the original engine to check out the trans, clutch and to drop in another crank with fresh seals.

Started with popping off the heads and pulling the cylinders.

You can see the 1.5 sq piece of wood for the in the exhaust port and the 2 lb hand sledge to "help". I also used KROIL to help break things free. The left and center cylinders ( as on the bike )broke free with a couple easy taps. The right cylinder was a little stuck towards the front of the engine. Tapping with the long wood and prying with the 2x4 in the intake manifold broke it free after about 10-15 minutes. I would get it up and smack it back down with the 2x4 on the top of the cylinder. Then back to the long board.

Pistons and the bores look pretty good.



I removed the spring clips and was able to lightly tap out the wrist pins while supporting the piston in my hand.
