If you start with a fresh engine. They can be very reliable, if you don't go trying to change port timing or compression. And excessive over revving.
The original crank seals don't last long with all the crap in the fuel now days. The new seals are made of a better substance.
The Kawasaki frame is very light and sometimes scary feeling. Not very sure footed.
It cost $350 to have the crank rebuilt.
The Suzuki GT 380, 550, 750 line of 2 stroke triples is interesting also. They have more mild power delivery than the kawasaki's which is in the bore-stroke and not easy to supe up. The 550 was kind of a let down power wise, but from what i heard the 380 and 750 (water cooled) aren't bad. The 750 (water buffalo) was the first water cooled street bike of the big 4 (Kaw,Hon,Suz,Yam)
The Suzuki's are way easier and cheaper to find.
The pipes are usually shot on the suzuki's, but you can have new, power increasing ones made for around $750.

I have found them to be as reliable as any other bike from the time period (and I have other bikes that were direct competition of the time period) Most bikes have the points type ignitions which if the gap is kept in check over the life of the points, I have never had a bike leave me on the side of the road. Performance is subjective, power is pretty peaky compared to other 2 stroke street bikes. Handleing is scary because the engines make a bit more power than the chassis can handle. IMO the 350 and 400 are the best "all around" bike. Those ride/handle well, stop well, and have the get up and go because they are so light. IMO the 750 is a stinker when compared to the 500 as it really doesn't feel much faster and is a lot heavier, it stops marginally better, however the 74 500 seems to be the year that technology (mostly braking) could keep up with the engine performance, but then the KZ1000 and KZ900 just took things to the next level along with Honda's and Yamaha's offerings.
I wish I had better and updated pics as some bikes in the pics are now either restored or rideable/legal "cosmetic" restoration process.
1969 H1 (500)
1973 S2 (350)
The bike before the tripples
1968 A7SS (350 rotary valve twin) Avenger
A few others 2 of wich are now in ridable condition.
Some Kawasaki Big Horn's in this lot (350 rotary valve single)
1974 H1 (500) now in ridable condition but still needs some cosmetics
Just for parts

I need to get updated pics of those bikes sometime. These were taken about 5 years ago. Some of the junkers are up and running.

Pretty sure that is a KZ400 not a 750.
Both pretty lackluster machines
