Beautiful porting. I did mine today after seeing this video, it's not so tidy, but have another 4 engines to practice the art on.

❤ love the music with it. Made it so easy to watch

great reference vid, love me some 77. A little trick when case matching... Instead of using a marker, cover the face with blue painters tape, then with your gasket and exacto, cut out the tape where you are removing material. It makes a much sharper line, and when your bit hits the tape, it will fluff up a little and you can clearly see you are at your edge.

Great video for an old good italian engine.
<<<nice work on it and nice music too!

Very wel done, ancwered lots of questions. And was abe to show 'helpers' how to assist me. :-)

[frederikropers]

how do you close that hole you make in the port of the case?

I think the direction of the seal on the main gear is wrong. the green side should be on the outside, sealing it off and keeping the dirt out. I never saw one puch maxi moped with the seal on the main gear installed in the way this video shows. And doesn't the brass spacers get stuck due to the heat? That's so far the only notice. I believe the rest is all done in the correct way.

Thanks for the info.I really enjoy your videos.

I used porting wax for my carbide cutters keep them clean you don't lose your indication mark like W40 can wash it away.... WD40 on the stones keeps them clean

Hi there... I have a puch maxi and the bearings just failed so I'm hopefully am going to rebuild the motor... How much money (dollars) is it to get new seals and bearings for the whole e50 motor

I use same method to fit main bearings but the pro's say to use a device to push them on.
also its good to match the transfer part of cases so that they line up with crank webs so that there is a smooth passage if that makes sense?

[nickburgherr]

how did you "flat out" the weldings?

[kyrox_official]

Schönes Video aber paar Fehler und fragwürdige Entscheidungen beim Zusammenbau...

PS.: viel Glück mit der Kurbelwelle bei dem Zylinder xD

[malteloman]

now start doing this kind of videos with all kinds of zündapp and kreidler engines!

[rottie]

got any great videos on tuning the m48 as used in the ariel 3 and batavus bikes?

[tpvalley]

reeed valve but only 4 transfers, why not have boost ports above reed valve?
and the tiny holes in the piston to feed crank case, could be bigger or cut a slot down cylinder?
Interesting little engine though.

from where you have these bushes on the stud

[mopeds]

Sure do. Check out our WSL pipe, and some of the kits we offer.

No polishing?? Still seems rough. Missing the first startup in the vid!? :-(

[airescamoes]

what happens if I don't grind the case?
