1957 Zundapp KS601 Images - The Engine From Rear Right

A little closer look at the Zundapp KS601 engine, gear box, and drive shaft. I apologize
again for the rotten pics. I really must get some from a more recent century, literally.
I had not yet learned how to work (or, apparently, even focus) my brand new 2.1 megapixel
leading edge Olympus, which has now been collecting dust in a drawer for a decade or more
after about that long of faithful service. Time flies...
You can just see the air cleaner, under and forward of the tool kit box, nestled in the rear
housing cover. Also, below the tool kit, the "Clutch Lever Bar" with the cable and spring
attached to it. This operates the double disk dry clutch, located between the engine and
transmission. Speaking of the transmission, there's the shift linkage on the side, operating
the somewhat bizarre double roller chain drive transmission. Attached to the tranny you
can see the U-joint boot and drive shaft cover, extending toward the rear of the bike.

some clutch, transmission, and driveline details.

As I mentioned earlier, the Zundapp KS601 engine was a refined version of the KS600. On the
600, there was one carburettor mounted about where the air filter is on the KS601, deep in
toolbox's shadow at the rear of the engine in the image above. So, instead of two air tubes
running between the filter housing and the individual carbs as you see above, there were
two intake runners running from nipples cast into the back of the engine casting. These
were directly forward of the tubes you see, above, coming out of the air filter housing which,
on the 600, was instead both a carb and air filter housing.
Those KS600 intake runners looked nearly identical to the KS601's air tubes, and may have
even been interchangeable with the 601, I don't know. But the interesting thing is that the
early KS601 engine castings retained the intake runner bosses, just not machined for the
tubes. I believe this was the case up to '52, if I recall correctly. My parts KS601 has
those cast bosses, so it's a '52 or earlier.
If nothing else, the ease of working on the KS601's carbs, compared to the 600, is one hell
of an improvement. It's a bitch to work on that single carb, scrunched up in the tight
confines behind the engine.
