I thought I would show everyone my last winter project bike. It is a 67 Kawasaki A7 350 cc 2 stroke rotary valve twin. It was in running condition when I picked it up in Spruce Grove, near where I live. It is a pretty rare model.

I stripped it down to the last nut and bolt. The engine was in good shape and only needed a few parts.

Chassis re-assembly. I used a rear fender from a newer A7 because I like the stainless better than chrome.

More engine detail. I used a Honda CB450 clutch cable left over from a previous project. It fits perfectly.

Nice job on the bike. Pretty sure you will have the only one lined up outside the bar, and it will get way more attention than all those stock and custom Harley's next to you. Mike

Nice bike John. I love those old two-stroke Kawi's and Suzuki's from the 60's. I did an old triple cylinder Suzuki for a guy several years ago and it was an anwesome bike.

Those rotarty valve engines are fun to play with the timing.

That is a very interesting and beautiful bike. Fantastic restoration! I love how the carbs are located on each side of the crankcase. Very unique and well done.

Not many of them around, I had an X-6 hustler (Suzuki) back in the day and those 2 strokes are great machines, quick enough too. That's true about the Harley customs outside the bars ...just pick your bars carefully.....

Nice job. I worked in a bike shop where the owner sponsored a few flat track racers back in the early '70s. We used to take those things apart, polish the exhaust and transfer channels as well as the whole bottom end. Then just shave a little off the head and we had some specs to cut the rotary valve from Kawasaki's road race team. The bikes ran in the 650 class usually won. Thanks for the memories, Bill

Thanks guys. I have some patch work to do on the seat base before the upholstery can be started. Hopefully it will be done by spring.

The more I look at that restore the more I like it , looks like an easy motor to work on well thought out.I am inspired by it to continue on the T150V I've been restoring for a few years now ....first the cams in my H-D though as It's my daily rider ....looks like you are a Triumph rider>

Very nice! I still wish I had acquired one of the Yam 350's. I note they are currently featured in the major cycle mags. I once owned a Zundapp 200cc which never did run correctly for me . Later Japanese 2 strokers really impressed. Wish they had been able to clean up the emissions . That is a great looking bike, but I would choose a different handlebar.

Great post
Had a 175 law enduro with carb in the side cover. It also had a compression release sounded like a jake break.
Sold it to buy a 500 triple law, wish I still had it.
Thanks ron

Just love spell check

That is my son's Daytona in the picture. I had a T140 for many years but had to sell it when the kids were little, everyone knows how that goes.


The handlebar bend is not my favorite either but it is kind of unique because it is an un-bent original to the bike piece and the switch wiring runs through the bars.

I have a Kawasaki triple (H1) project on the go right now too, I'll post some pics soon.

Verrry nice restoration on a very cool bike. Those rotary valve two strokes were screaming machines. I had a Kaw 100 Centurian race bike that was a single cylander rotary valve two stroke. For a 100 it was scary fast. Raced it for a couple of years and won lots of trophies. What a blast.

Jeez...that's a great job !!! Ya just have to tell me what the process was for getting those cases, cylinders and heads look so fresh. I've got my '75 Suzuki GT 750 Water Buffalo waiting in the wings for a total resto. Thanks for the pictures.

Thanks for your comments. All the parts were stripped of their original clear coat finish with paint stripper (Polystrippa brand), then glass bead blasted and finally painted with Duplicolor engine enamel and baked at 250 degrees for 1.5 hours. This leaves a very hard finish that is very chemical resistant. This is the same process I use on all the bikes I work on and it has proven very durable.

What a cool bike. Thanks for posting. Like everyone says the 2 stroke rotary valves are a hoot. I raced Can-am dirt bikes years ago and still have the scars to prove it. They were brutally fast and only wanted to go faster.

Nice- brings back memories- I had the little brother A1SS 250cc; ran the p*ss out of it. We called it the "ticket bike" ; everyone who borrowed it for a quick spin around the block invariably came back with a speeding ticket. Good times.
The banjo fittings on the oil pump are delicate- be gentle when tightening those. And the three-ball clutch releaser is kind of a weak point- you can see the case bulging from the force. But it works. Those rotary valves don't quit pumping fuel mix at high speeds like a reed valve design, gives very high RPM- they do wear though, and the case halves too. Enjoy.

Nice job on the Kawasaki John, I've finished a few Suzuki's lately maybe I'll post some of mine.

Back in the early 70's I had a 1968 Suzuki T20 Hustler 250cc, sold it to a racer friend but wish I'd kept it along with a few dozen of the bikes I've sold since.

Here's my lastest restoration 1981 Suzuki GS 650E took about 9 months to finish.

How I found it, after I pulled all the stuff off of it, stored here for 30 years.
