Hello

[Det]

OK. Thank you.
I need a new cylinder as the old one only has about half its fins so I need to be able to order the right part.
The engine is completely seized and getting the piston out of the cylinder did a lot of damage. I've not gone any further with it yet, but I'm expecting a lot more problems.

I've been in that area too, a few years back, with the car (and a board on the roof - windsurfing on the Black Sea), we went from Burgas --> Thessaloniki.
Sounds like you picked an adventurous spot to live!

See blurredman's FTP site for a workshop manual, or miraculis.de for one in German. To find out which model it is, compare what you see on your bike with the data in the manuals. A barrel may not be cheap though.

Good luck with the house!

I'm hoping to find a used one. There are a few places in Bulgaria that do parts for old soviet motorcycles. Thanks for the link, I'll certainly go and take a look. I've had the bike for a few months and it got buried at the back of the workshop when I had stuff delivered and needed some storage space. I'm planning to dig it out after the weekend, so I'll be able to have a good look then.
Burgas is quite a nice city. Bit big for me though, I like the countryside.
Our house is about 20 miles from Yambol which is the nearest big town.

Sorry, I Can't get that ftp link to work.

Sorry. I suppose it could be a 175. Unlikely to be a 300. But I can see from the design of the bike it is a larger capacity engine and not 125cc etc.

I could measure the piston. I'm assuming the bore/stroke size denotes the capacity. Or is it possible to find information on the bike from the engine number? I remember from my MG days a friend was able to get lots of info based on the chassis number.

Hi Det,
many modern browsers do no longer support FTP, you can access blurredman's FTP site with, for instance, K-Meleon Portable (try https://portableapps.com/apps/internet/ ... n-portable):

You want the ES manual, I do not know the difference between the 2.

Miraculis has MUCH more, and these are the scanned original manuals, in HTML. You might be able to read them in English via a modern browser (the text, not the pics).

Yes, SV = ¼πB²S, with SV = Stroke Volume, B = Bore & S = Stroke. All ES 175/250's have a 65mm stroke, for the ES 300 it's 72mm. The latest ES250/2 had B=69mm (making SV=243cc), the earlier ES250 & ES250/1 had B=70mm, giving SV=250.15cc - a minor legal issue. Of course B changes under a rebore.

Yes again, there is info in the VIN (like the date of manufacturing), but I do not know the details for the ES.

As we're a bit beyond the saying hello stage now, please continue this thread in the Vintage area viewforum.php?f=5
