Maarten's Kreidler Club!

Hello Guys, I finally obtained some news from Powerseal, my both cilinders are by their shop since few week now... : They are still telling there is no problem on both. When I ask why the honing is getting polished and glazed after only minutes, there is a sort of embarassment or unclear. Cause they...

Hallo Carsten, Danke für deine empathie, glück dass Arnold, Wietse, und euch, etwas über fräser und drehbank kennen. Bin ich sehr überrascht über des Rito Defekt. Ich war ziemlich zuversichtlich, wenn früher Arnold mir die 12mm pleuel auf die originale Kreidler wangen montiert, ins besonders dass ei...

This 340 Street Number i did not know, but I first thinked of this when saw your pictures :

Fa. Intermot Verkaufs AG, Förrlibruckstr.181, 8040 Zürich

That was were the 1974 RS of my Friend was sold, confirmed by Rudolf Scheidt

Good to see those old pictures, but unfortunatly of a closing shop...

Good evening guys, few weeks ago I was planning to drive to Nederland, determined to resolve all of those problems I had with that engine. I was waiting until it will be finish to write, but anyway, it is not done yet. I cannot resume it by few sentence’s, so If you have no patience to read this lon...

Hello Guys, Thank you for your support and the interest you are giving to my Kreidler. In this tumultuous engine overhauls, I can say that I have the luck to find passionated guys that are helping me. Arnold, Wietse, Claus, Carsten, Michel, Enzo and sure I forget some of them ! Carsten, this red Hon...

Hello everyone, I try a small resume about this engine, I am still searching someone to make me the geometry job, Unfortunately Arnold is not interested anymore, i waited, he was proposing me to do this job 2 month ago :/ I had no time, I make it now... LVS I dont know yet, maybe already busy with l...

Michel, here a small video of what I thinked for a 3D Printer job, sorry for the english, I tried...

Hello Michel, asked LVS for cilinder work, and I will see maybe with Dick Baan for bottom end, wait LVS before to know :) The thing you say about machining a groove for O-Ring, I am dumb, you know what ? Because when LVS did my work, we made an exhange. I gave him my old damaged Mahle 15.43.26, and ...

Your right Michel, nothing more annoying to see your Kreidler not working a whole summer. Last year it was like this, grounded after my surgery, zero motorcycle the whole year, and i only enjoyed it for a week end in end Oktober... need to make this working good this time, it is going on nerves, and...

Good evening guys, I hope you are doing it well, and wish you the best for 2019. Caspar , i note that for piston rings play. Also mine were to wide. I had 0.15 and 0.10. First eror for the brand new Nikasil... Second is that the Meteor had less than 0.03 of clearance. Third may be (90% sure) an alli...

Hallo, Ed.p, I cannot say you yet the space between needle and piston "walls", but your theory seems right, because I had a small movement possibility, like to get on a side or an other, but also not so much, to say, note more as my 125, but this INA is also for Mahle, maybe not for RITO +...

Hello, Michel, this is what I wanna make, because measures are showing me that it is already worn, exactly in same area as last years, around poorts. I can understand what you are saying about strong of Kreidler, My friend has a 20000km RS, his bore as still the factory values... and still 0.03mm of...

Nozem, I measured few times compressie to compare and write in my report (Kick + Vollgas opening) Before first Start (Also oil that increase the result I know) : bit more than 9 bars After first 20 km : about 9 bars After about 200km when bougie check : same 9 bars Last ride when i felt the bike was...

Sure Nozem ? I like what you said about your cilinder that honing spuren are stile there after 30000km. On all other bikes it was like this too, except on this Mahle. For the Rich mixture who flush oil film I know this reality, but I never made more than 1:25, and of course with a good oil (Anyway, ...

Hello everybody, it seems like I go back to last year... I rode 300km this last week end, it was perfect, more than 90km:h, was very proud of this 40ZN17...almost 100 on GPS for a 50cc, I could't expect more ! Unfortunately Tuesday when getting back to home after work, I wasnt able to go more than 8...

Hello Guys, I must be morron, because this play I can see by eyes on piston rings : https://www.youtube.com/watch?v=f1654aKbYhw When I take my piston in hand, I can measure only 0.05mm of axial play for the L-Ring, and less than 0.04 for the second one... don't know why it was so visible in cilinder...

Hallo Carsten, vielen danke für erklärung. Für den gerausch wiel ich die top end wieder demontiert um die ring spiel zu messen, weil ich muss wieder einmal des kopfs dichtung wechseln, also werde ich in selbe moment machen. Dass verstande ich nicht, zylinder hat seine ganz perfect dichtung surface, ...

Hello, this morning I went to work with the Kreidler, but i don't think i will do it this afternoon... I dont think so that this noise is normal. We can barely ear piston rings vibrating.... damned why ? https://www.youtube.com/watch?v=0td2ge1lvpA I saw that i wasn't only Meteor user with this : htt...

They where ok, I always check on different "orientation", but cilinder is also new, no oval. Gap of rings is correct, they just have this crazy play on their own piston. You know a "limit" value ? I never felt so much play on a brand new piston.

yes of course, everytime I mount a piston in a bike ! they are between 0.10 and 0.15, perfect ! (With Mahle I got about 0.40mm, to much, brown piston, was leaking !) The problem, if it is a problem, is the gap they have IN the piston, you can see it on my video, that noise, and we see them moving. B...

Hello, last weekend I made again engine, to reduce axial play crankshaft to zero ! No more radial play. For the pistons rings I dont know, it is brand new Meteor, today made 20km, everything is working fine, but piston springs are noisy, that wasn't present with the old Mahle. For this "suspect...

No Enzo, this ticking is not from primair gear and clutch, this come from top end on the pistons rings.

Ich werde nochmal sehen, wenn es heiss wird, weil ich erinnert mich nich solche problem letztes jahr mit diese nachbau auspuff...arfff Her a smal video of the Meteor, the sound I ear come from thos piston rings. First time I see so much play, but this is new so i must be worrying for nothing like mu...

I have an idea, maybe crazy but. Last week after my 3km ride, i dismantled the exhaust just after coming back to home, when it was hot. Maybe the bocht is now "verbogen" a bit, because i removed when it was hot, possible, a let him cool in the workshop ? That could be the reason, because l...

Hello, the pistons rings are those who come with the Meteor ! Just cheked the clearance and mounted them... i did not eard this last week, maybe i missed this sound, this is crazy on a new piston or ? Today I have another mystery... last week before dimantling again, and even last year when I rode, ...
