    :cry..I'm pretty "bummed out" that I have to leave the bike sit for a couple of months while I'm out of state for work. Haven't been separated from my MC's for more than a few weeks ...ever. :cry.....The bike projects have always been my favorite pastime in my off hours. It's gonna suck not having my "friends" nearby.:cry..I'll be going nuts....:happay

    My very first scooter was this model. Made it go almost 60mph.

    I had an old Puch Moped that looked almost exactly like that. That little thing went like hell! It would do right at 60mph with the 65cc kit, carb, porting and chamber I installed on it!

    Zundapp apparently realized the importance of marketing...some pretty cool ads:

    Well I'm finally back "home" after a 3 1/2 month separation from my projects.
    I spent a little time last night and installed the replacement transmission linkage I had purchased. The old linkage had been jury rigged and it slipped on the shifter rod. This bike has a left side shift lever, with a rod running through the transmission to the right side linkage....the earlier KS600 bikes also had a hand shift lever which attached to the linkage shown. The linkage below was split at the bottom and a PO had used pinch bolts in an unsuccessful attempt to repair it. I found a decent used linkage assembly, although not very cheap......but then nothing is cheap for a Zundapp KS.

    I found this reproduction headlight ring which is a replacement for my very banged up and dented one...I'm finding it difficult to replace functional, although beat up, parts for shiney new parts. Just doesn't fit the patina.

    I plan on tearing into the engine top end again pretty soon to see if the 3 1/2 month oil soak has free'd up the pistons in the bores.
    I've found NOS Zundapp over size rings for around $50.00 a set. They sell them at .10 - .30 oversize which is good.
    I always buy oversize rings and then file them down to the exact ring gap tolerances. Hopefully the pistons are OK...we'll see when I make my next post with some gory, disembowled Zundapp engine photos.

    Damn Wacker you sure know how to pick 'em! :wink:

    I just acquired a 1956 KS 601 EL and I'll be following this thread closely.
    Never seen one before, never wanted one, didn't even know they existed.
    After taking a first look at mine I knew I couldn't pass it up.
    Hoping to rig up my ACAP sidecar and roll up some serious blacktop miles (probably some browntop too!)
    These are serious machines, more expensive than a BMW to produce and Zundapp refused to compromise the product in order to compete in the new markets of the late 1950s.

    I am a Zundapp Fool! Let's get 'em running!:freaky

    Cool, The EL is super rare from what I've heard ...only a few hundred of them built. I'm hoping to have some progress on my project in the upcoming weeks. How about some photos of yours?

    Will do, as soon as I can get it all in one place.
    Spent last night til 12 sorting thru masking tape labeled twist tie sandwich bags from 1974 looking at all the goodies that were put away.
    The guy I bought it from is 74 and has trouble with memory....
    I'm missing one box with the top triple tree, rear fender lower section, plate holder and a few other things.
    Complete exhaust system is at another garage he stored things away in 1984....
    Hope it all turns up.

    Wow ..kind of like an Archeological Expedition! I love stuff like that. I was fortunate to obtain mine in one piece. My goal was to have my engine running this Summer but now will be Fall at the earliest. And that depends on internal engine conditions...:confused.....Prepare to lighten your wallet.:lol3

    Hoping for the best on the engine. Intake and exhaust ports were blocked off with blank plates and rubber at the time of disassembly. This was a running bike stripped down for paint. Don't think it was broken. The engine itself is one big lump. Appears as if it has never been opened. All fasteners are unmolested. Someone took a great deal of care taking it all apart. Everything is marked and labeled. I can hope but who knows until I open it up a bit more....

    Had a moped with a fan-cooled Sachs engine that looked identical to the one above. Mine was 2.5hp in stock form, with a 60cc kit and 17mm Bing carb it was supposed to be around 7hp. Never had the $$ to obtain the correct ex. pipe so mine was maybe 5hp on a good day.


    Yeah , The KS sure sounds like quite an impressive bike.
    I read that it actually is a 170 degree v-twin. And cost 2x as much in materials and time to produce than a kübelwagen

    Mine has a number of improper fasteners, miss matched here and there.
    I bought a "complete shop & rebuild maunual" on CD via EBay for $20 + some odd bucks. . When I received it , it was actually a copy of a riders manual and did not go into much technical info. on the mechanics of the machine. I later found the same manual free on the internet. So beware of that scam.
    The "Zundapp Fool" will be of great assisstance on your project. He has a real love for the EL Models and has one or two of them. They are the "Holy Grail" of KS601's in his opinion due to their rarity. He has a lot of used spare's although not cheap....but he will deal a little bit. He seems to be a real nice guy and is a great source of information.
    You will be WAY ahead of the game if the intact engine is usable as is. Hopefully moisture didn't get to anything. Can't wait to see some photos!

    Got an order into James (the original fool). It's hotter than hell in Texas so I'm being patient.
    No doubt he is guru and is dedicated to the marque.
    The frame is powdercoated, the rear wheel swingarm, shocks and engine installed.
    The front end is all there as a unit, just as it was slipped out of the neck decades ago.
    Tires have air in them.The seller has misplaced the box with the top fork (triple tree).
    The bike was disassembled in 1974, and he has some some long term memory problems.
    Got the sheet metal and exhaust home this week (they were misplaced) but the big lump is still in the sellers shed.
    I want to roll this into my garage so I'm waiting for the replacement parts.

    I've been cleaning up the gas tank, checking out the carbs, controls, drive shaft etc. and doing all the research I can in the meantime.
    Getting quite the education. Zundapp couldn't compete in the market with BMW's low price.:lol3
    Pretty excited about it all right now, this could be the last bike in the stable.
    Not that I won't acquire more but it could be the last to go when I'm too old to roll.

    I'm hoping this Danish ACAP will be a good match.

    I should do a good job of documenting this bike, maybe I'll get some photos of the parts I have and slip up to the farm to get some shots of the big lumps this weekend.



    Here's a link to what I'm looking at, mines all black with gold pinstripes and just the right amount of dull pitted chrome..... this is not the bike.

    Wow, that sidecar will be a wonderful fit for the EL.:clap
    I have a Jupiter sidecar with a scratch built 1000cc BMW Airhead attached, but the Jupiter looks a bit too modern for the KS601.

    Seen your rigs, followed your builds along the way. Your airhead is superb.
    You were one of the inspirations from my first build, the "Greevorex".

    What have you heard about the performance of the KS 601s?
    I'm hoping to be surprised, James says these were the hares compared to the tortoise BMWs of the time.

    Took a few photos, wish they turned out a bit better, but this should give you an idea what I'm working with.
