Good evening gentleman (and ladies if present!)
The address/link is https://mz-forum.com/
The forum is very big and informative, its free to register and if you use Google chrome and use the translate function, it’s a good read.
I can’t find the original post as the listings for “Kickstartersegment” are very numerous.
In reply to Derek’s post…. As I’m a bit obsessed with the DDR in general and IFA motorcycles and scooters in particular, I like to belive that any good bike engineering solution MUST have originated from the MZ factory! (a bit biased but it makes me feel happy!)
Regards, Neil
Good morning everyone!
Further to my previous post, I refitted the original regulator (it did have a solid state one purchased from EBay) and the bike now runs and charges beautifully.
(I think the moral to this is ‘Stick to MZ components….the factory definitely knew what it was doing!
Kind regards, Neil
Hi Derek
Many thanks for the reply and grovelling apologies for the late reply!
The brushes are quite new but as I’ve been running the engine, the charge light do grow quite dim as the revs rise. I assume this may improve as the commutator contact area on the brushes bed in and increases.
Many thanks and kind regards, Neil
Hi again!
I’ve just realised that Membership Mans earlier reply mentioned most if not all of my previous post…….I really need to read posts properly!
Regards, Neil
Hi everyone!
I seem to remember reading somewhere that ES125/150’s used a brass bush little end so needed a 33:1 mix but was changed to 50:1 as the newer TS’s used a needle bearing little end. Also did the 250 engines change in the way the main bearings were lubricated? (Lubricated by petrol/oil mix as apposed to the gearbox oil or visa versa)
Any thoughts/opinions anyone?
Regards, Neil
When I originally opened this topic, I didn’t realise what a big can of East German worms I’d be opening (and I only enquired on behalf of a friend!)
For the record my old DDR machines run on 25:1 and I shall be continuing to run it on that mix, I think that modern 2t oils burn more completely than oils available in the 1950/60’s so they won’t smoke as much, although a nice faint haze from the exhaust is very evocative! And as I use Putoline strawberry scented oil you also get a faint but nice smell of strawberries.

Good evening everybody!
Many thanks for your replies, I quite agree about only saving a marginal amount of money (I think you’d have to cover many, many miles to show any significant savings) and since the only way to see if it’s a needle roller bearing or brass bush is to strip the top end……rather pointless if everything’s running ok. I think I’ll leave everything as is.
Besides……a gentle haze from the exhaust drifting serenely across the countryside is rather traditional with a MZ!
Kind regards and many thanks, Neil
Hi Brian
Sorry for the very late reply but I used your suggestion and……it worked! The exhaust port is now leak free. Many thanks for the advice.
Kind regards, Neil
Hi there!
Many thanks to you both Stefan and Derek! Hopefully I’ll get it sorted now that I know!
Kind regards, Neil
