Hello,

thanks for your support, it motivate me more ;)

A bad new for the sand in the frame, I have it on each wall. I tried with airpress and a vacuum...nothing get out..... #-o

I have to dissasemble everything....Not so much parts but makes me nervy..

What if I rince the inside with a Kärcher and that I suck out the dirty water with a water vacuum at the same time ? Like puting water by the two inlet hole under the seat and sucking the water from the airbox hole ? After that I defat with acetone or some cleaner and immediatly treat the inside with Tectyl to prevent corrosion because of the water ? What do you think ? Good or bad idea ?

Meanwhile, I've finished the Ignition :

And with this Electronic Box (After 1977 ?)

We wired the ignition with my father, and I got a nice blue spark ! Problem, she didn't appears at each Kick....maybe just a ground issue...Hope..

Thanks, Best Regards, Florian

You can clean up with water. And dry not with agressive aceton but try spiritus ( akcohol).
You ignition coil is the early one and is extremly weak.
Try to find a later bettter ignition coil.


Of try with a test ride it is good or bad

Ok for the sand, I will clean it next days, I need time to dissasemble the thing, and I haven't time yet :/

For the ignition, the old from 1973 is better as the "schwache generatorleistung" from 1974/1975 ? My Coil look actually not very good, I have the one of 1200ohm, with half covered copper... I understood that old original Bosch are out of stock ? I'll better find a complet modern Ignition instead of Bosch parts ? :|

I maybe just have a bad ground.....because I had few blue spark, but alleatory...

You ride with what ? Kokusan ?

Thanks

What do you mean with bad ground?

This is not the right montage !!!! with no rings. That is bad and the only ground point!

I mean that when I touch the blok i've random a blue spark, and sometimes nothing when I kick.

For the montage, we didn't see on photo but I have the rings ont both screw. For the "ground", I see on my Schaltplan that the rear stop light is ground/earth :

Afbeelding

May I link the blok with a ground cable on a Carter screw (Brown cable) ? When i dismantled the engin, I had a cable linked to a carter screw, but I don't remember if it comes from electronic box or something :

You find original Bosch coils today ? Or riding with a modern Ignition ? If my Ignition work it's fine, but how long would it work..

Thanks

I know what your mean :wink:

When you look to the picture of the new coil you see two connections.
One ring for grounding on the housing and the red wire to the electronenbox


You forgot the two grounding points on the cocotte for the front lights ! And the 5 on the MHKZ coil housing

The clips for grouning on the motor is not for the 1973 model
This is for later weltmeister type one grounding wire to the cockpit and the other to the rear light.

Your grounding is motor/frame connection with bolds

I see a lot of parts for your ignition type but not you wanted

And here you see the completly madness of today.
http://www.ebay.de/itm/331718180548?_tr ... EBIDX%3AIT

I buy this coils between the 15-30 euro's

Waouh, 120€ ....Crazy ! A bit more and I got a complet Ignition or ? So My wiring is correct ? I don't need another ground/earth connection ? Also I should find why Am i getting random sparks.

Prices are crazy....expansive just because old....did you see what sellers ask for a Kawaski 3 cilinders for exemple..... :?

Thanks for support

P.S. But for grounding, how should I link Coil housing (5) with frame ? And my blok is a 1979, does it change something ?

You can take the motor connections for EXTRA grounding. One for the rear light.
And the other to the frontlight (lampconnector)


Than you have no problems with dirt, rost and to mutch painting on the frame

Hello, thanks for tips. So if iv'e correctly understand, I should ground the back light only, and i can do it to a carter screw ? Should find why I'm having random sparks > My ignition coil is grounded to the ignition plate...OK, but were should I "Ground" my blok ? Or the blok is just connected to the frame with the 3 axis/pin ?

I've dissasembled the frame today....ready to be cleaned...It's not so annoying to begin again, quickly down, no much screw. I love the practicality of a Kreidler.

I'm on vacation next week thus i'm going to continue the thing. About the frame cleaning, i've some question about the Tectyl.

How would it hold on frame inside walls ? Because frame holes are small to put the spray bottle and aim each faces...How are you treating your frame inside ? Is the Tectyl colored, to see if each walls are covered ? Im gonna see if someone could lend me an endoscope camera...

Problem, when I will rince the frame, the dirt water full of sand will go everywhere, and I've already installed the Neiman for the stearing...should try if I can remove it for the cleaning....

Thanks, Have a nice Week, Florian

Try another Bobine (outsite )
Try a new Spark plug
Buy and fit a new and better than your version (weak) High Voltage coil
( the second one in a week for buying http://www.ebay.de/itm/151910471924?_tr ... EBIDX%3AIT )

Hello,

my spark plug is freshly unboxed.
I will try with an other Electronik Box when i will remount the thing.

Today I cleaned the frame with a Kärcher for about 3 hours of water pressure.....It's clean in the area of the Airbox opening, but When I rince the frame with brake cleaner, sand still get out by the front opening (Neiman, steering...) I cannot put the Kärcher hose to the front of the frame...The back is clean...but what about the front...

Im afraid that because of vibration, the remaining sand will fall to the bottom of the frame, where the airbox suck air....

I Received Tectyl ML this morning from the post. I used the nozzle with my brake cleaner to "finish" before treating...but there's still sand in the front.

I think the Textyl wax will maintain the rest of sand, but not sure.... What is your opinion ?

Wee see on the picture that the airbox intake area is now clean....but begin to rust !

Hello,

your'e right. I rinced for few hours the frame with the Kärcher. Today I've sprayed Tectyl ML with the nozzle. I don't know if each walls are covered because before drying, the fluid sink to the bottom. When it's dry, it let a yellow wax. Remaining sand is in the front near steering, I hope it will cover it. I think I put in too much Tectyl.

Tommorow I can mount my Kreidler Again :)


An other question : Im actually overhauling the two wheels (36 new wire per wheel, with a new circle) Old are rusty and cracked.
Afbeelding

I just keep the Drum..and about the Drums, they are ovale... My boss can adjust the thing on a Lathe, but I need to find an axis whereby I can attach the drum with nut for exemple.

Afbeelding

I cannot use the original wheel axis, because of the edge or ? (To put in the Lathe chuck) * Not my picture
Afbeelding

Anyone as already corrected a drum on a machine ?

About my brakes, my rear isn't a Leleu. Iv'e the chance it has the same diameter (Only the lid is smaller, but brake shoes have same wide in neutral position)
Afbeelding
Afbeelding

But from where it comes ? A Sachs, Hercules ? I thought it where a Zündapp and I purchased new shoes, but they are much smaller (150mm)

Thanks, and Happy New Year ! Florian

Wheel axis is from the front. It is the right one.
46 mm is the thickening.

For the back you must buy a 160 mm LeLeu

This Drum fit on the wheel, but I don't know where it comes :/ ive already purchased two circle 67.89.02 and the 2* 36 wires to overhaul mine....

If i put it close the original Leleu, it has the same wide, same height. It would be useful to replace brake shoes, but I don't know from which moped it comes.

This complete wheel look in good shape, but I've already spent a lot of money and I have already the parts.

Any Idea for this unknow Drum ? The inside of mine look like this Hercules http://www.ebay.de/itm/Bremsnabe-Bremst ... 0846693310

Hello,

The Kreidler is re-mounted :) I must finish the electric beam and cables, and I must try to start this week-end...

About the cables, I'm bloking on the Clutch....how is it supposed to work while settling the cable on the frame rear near the mudguard, instead of pulling the Clutch "Hevel" ?

Is the sheath supposed to push the "Hevel" ? I don't understand the original montage...Iv'e Lusito copy levers, It can't pull the hevel if the Sheath is maintained on the lever tensioner ?

Iv'e Found : viewtopic.php?f=4&t=44065&mobile=mobile

But how will it move on my Lusito levers ? Don't understand

Thanks ;) Florian

P.S. I'm used to buy my 2 stroke oil in a supermarket for my 125 who's lubricated by a pump. This oil isn't from a Brand like Motul, Motorex....but has the same JASO/ISO quality standard. What I like is that I didn't pay much for the brand and the package...a 2 Liter can cost me about 10€, when a Motorex 1L cost the double !

I never used mixture oil. I don't wan't to do bad economies to destroy my blok. Just wanna know which Oil you use to mix with your gasoline. In my area, I can buy Motorex, but not shure if it will be adapted (100% Synth) and it is expansive.

Speaking about oil ? It mean an imminent start....I hope :D

Hello, the start of the blok is approaching, but with some problems :/

I've now a good blue spark (I've connected ground to a carter screw) and the fuel/oil mixture is coming the cilinder (I have it on the Bougie)

Problem, It leak on the top of the Cilinder/Cilinderhead. I feel some air comming out, and it squeak :

https://www.youtube.com/watch?v=-1EJBGv ... e=youtu.be

All gasket are new off course. I've tried with 14, 15 and finally 16Nm for the head, nothing change, the mixture spurt out.

I haven't mounted the gasket with a liquid gasket. I think of a bad head surface....but it's very strange :/

Any Idea ? Thanks, Florian

Hello,

my boss made me the cilinder head flat (It was effectively veiled)

And the thing started ! https://www.youtube.com/watch?v=aoAiLTRv0u4

Im very happy to hear this sound ! But it is fat between cilinder and cilinder head, i will give him the cilinder to, to make it flat.

While waiting for an other start, Im working on the electric beam.

First, i don't find where to buy those cable lugs for my electronic box, we don't have those size at work.

Second, I have this "Stuurshackelar" and i don't find any shema for mine.

My question : Can I use juste the first of the 3 position of the GUIA to make an anti-theft circuit breaker or is the battery essential for the GUIA ?
