Yesterday didn't happen, too worn out studying Zundapp offerings on the internet.
I did clean the heads up at work in the brand new green parts washer... I can do better in a sink with Dove and a toothbrush!
It was OK but I miss the old carcinogenic solvents... so much more effective.

I came home today with every intention of buttoning the heads back up and poring a cup of PB Blaster in each spark plug hole.
Letting it soak a while before attempting any movement and doing some damage.

It was warm today in Nipomo so first thing I clicked the gearshift around a bit to see if I could engage and disengage some gears. 1 N,2,3,4.
Seemed good and the more I did it the easier the snatches became! More defined. Repeatable. XLNT.

Went about spraying a bit more Liquid Wrench into the bores and decided to give each piston a solid whack with a hardwood dowel to shock the fluid into the bores.
First whack I could see the LW jump a bit, like a sonic wave. Went to the other side and did the same. The pistons began to stroke inwards. On their own. Wow.
Gave the kickstart a gentle push thru and it revealed two shiny bores with little or no scoring.
Bottom dead center, spray, top dead center, wipe, repeat. Twice. Three times. Four.
I'm gonna put the heads back on tommorrow and do a compression test.

I is one happy camper this evening, great start to the weekend.

"I miss the old carcinogenic solvents"
I'm right with you on that one. remember when Gunk engine degresser would actually degrease?
About 25 years ago my neighbor drug home a lump of Zundapp, a 54? 600cc if I recall correctly. He spent the next year restoring it. We had a heck of a time getting it running until we found a float full of gas. we drained it and solder the joint and it ran sweet as a nut. Really neat bike in my opinion.


When given the choice between two evils I picked the one I haven't tried before

The 1955 R50 and R69 both had swingarm suspension. I read somewhere that the 1956 R67/3 was the last of BMWs plunger models.

Don, that's gonna be a cool bike! Lookin good. Keep posting the pics of your progress!

Great find! Love it. I fought another guy in a bidding war for a Zuendapp/Horex Imperator a few years ago in an auction. He wanted it more than I did so I didn't get it.

BMW did in fact introduce the swingarm suspension in 1955. BMW knew that the customers who were dedicated to BMW did not like change, so they made the shocks on the 1955 - 1969 models look like plungers. They were swingarm models with vertical shocks though. I have a 1961 R60/2 and it is indeed a swingarm rear suspension with an Earles front suspension. The line included the R50, R60, R50S, R69 and the R69S.

That is one cool bike! If the "Britbike Forum" was gonna make just one exception for a non-Brit on board, that Zundapp is the bike. It's the only bike I'd even consider trading my '59 Bonny for. Not offering, just sayin that's how cool it is. You are one lucky dude.

Not quite up to date but much progress since last August.
Hoping to get some combustion soon. Lots of assemblies, lots of discoveries.

I'll add more as time permits.

Have you discovered whether parts are available at all, at all? That seemed to be the concern when we left off last year!

Looking forward to seeing the final result, and hearing about the ride!

I stopped believing for a little while this morning. Journey is really going to be upset.

Parts are out there, Germany, Greece, New Zealand and even here in the US of A.
I've only had to source some sundry items, most of the original hardware was labeled with pencil on masking tape and put into
twist-tie baggies back in 1964 or so.

It was about 92% complete.

The previous owners drained the oil, backed off the valves, fogged the engine and then blinded off the intake and exhaust ports leaving the pistons at TDC. They did a textbook job of recommended long term storage. Took months (even with all that) to unseize and clean it up. Remarkable engineering. These are the folks that refused to compromise their standards to meet BMWs low prices.

Couple of more photos. I'm playing with the passenger pad. Making a rack/mount out of 7" 6061 Aluminum Association.




First come the paper dolls, then the mock up, then I start cutting the alloy.





The oval saves some weight and creates a nice reveal.




That's just paint on the plywood I'm not ready with the holesaw/bandsaw/jigsaw/drumsander/belt sander routine just yet.



I followed the same procedure on my plate holder, and added some BA9 LEDs for additional illumination.


















I'm pleased with my progress.

that frame has nice aesthetics in the back, looking forward to seeing how it all turns out! quite a minimalist look so far ;-)


just looked at your slideshow, we should go ski sometime when we're both in the same area!!

Saw this on the wall of a buddy's garage- thought you'd be interested to see it.







Now, all you have to do is find some crash bars
er- I mean engine guards laughing like the ones pictured here...

Thanks for that Tom.

Got the engine guards and like everything else they are a little weathered. Not sure if I'll put them on or not.
With a sidecar I probably wont need them and without I'm not sure how I'd continue to perfect the precision head grinding the previous owner did while cornering. Got the Domi poster also. One thing I do not like is the BA seat. Spoils it for me.


Snowbeard... the EL does have pleasant form and flow with the frame considering
it was just their plunger frame modified for swingarm installation.
I'm trying to keep it understated by making everything appear as if it could have been in 1956.
Any suggestions on the seat pedestal design are appreciated.
Patina is hard to come by and even harder to create.
Most of the chrome is dull and pitted. Parts of it are worn down to the copper.
Looks good to me. I'm going after the scruffy class.

Love to go skiing. Mentioned a while back that I lived in Dillon for 10 years.
I'm still on K2 712s with Marker Rotomats and Lange XLRs but I could carve a few more turns...
Skiing is one sport that you can continue into your old age and I'm only 56!

sounds like I'll have to strap my skis to the A10 for the 2014 rally! wink

The hubs are just great! massive, but very nice styling. Hopefully they allow for really strong braking too!!

I like the look of those guards as well, continuing the swoopy lines. you may not need them, but they do seem an interesting bit to add.

nice work!

In my kid racer mind it looks more like a Dragonfly than a beemer to me. More gizmo's it seems. Crash bars could be powder coated maybe? the shapes are worth putting them on.

It does resemble a Dragonfly Steve.
Just a little bit larger and with twice the horsepower.

I was thinking about powder coat on the engine guards, maybe even an alumicoat that hotrodders use on exhaust. Glad I have a set for patterning the at least.

From a couple of weeks ago... got spark, nice and bright.
Need to check a few more things, finish off the wiring, set up a test fuel tank and then see if I can get an idle.
Little bit frightened, little bit excited.

These Bings if not worn should give very nice even idle.
Did you clean them thoroughly ?

Yes, twice.... maybe three times.
Full soak in Berrymans, soda blasting, more air and Berrymans again. Keeping my fingers crossed.

Less than two years and I'm on it's 3rd tuning. Came together very well. Odd bike, not sure what to make of it.
Sounds like my Lightning, handling is actually fairly nimble.
Feels like a propdriven flying machine with lots of torque for pulling out of and into dives.
Kicks over like a clock winder, there's no need to get it up top on start.
Just a gentlemanly roll thru will set it ticking over.
Draining all fluids again this evening after some naked bike hooliganism around the block.
Checking valve and other gaps again, again. Twisting some needles with knurled tips.

Sheetmetal is out getting the pinstripes refreshed.

Like my 1/4mi. tank?








Out on the lawn last week, oil pan buttoned up..




The filter in the sump




Yep, I'm riding this...




I'll edit some video with good audio soon.

Don, it really looks great. It's a unique machine with terrific lines. I think you took just the right approach to bringing it back to life. Looking forward to your video.

And yes, I do like your 1/4 mi tank. I looked all over for something just like that a couple years ago, but came up empty handed. What is it from?

I think it's a starter tank from an old Allis. eBay $25 delivered, no tax.

I like using the "tuner tank" makes getting to all sides from one side easy. Fenders off is great also, no annoying sheetmetal for additional resonation, just pure mechanical mayhem.

Spanners and feelers flying as I dial it in.

And one more question if you don't mind. How did you get the alloy looking so nice? When raf940 redid that 67 R69S, he said he used a couple light dustings of Rustoleum Cast Aluminum Engine paint, and it looked perfect to my eyes. Just wondering what your method was on the Zundapp?
