[Grand Designs] project - my ETZ 250

Postby dirtsurfer » Wed Feb 28, 2018 4:08 pm

I drove up over the mountains yesterday; the last day of summer ; to pick up a 1985ish ETZ. It is missing a few parts and its in pretty poor condition. I'm told the motor has siezed. So I'll have plenty of work to occupy my time over the next few months

Good score.
Enjoy the rebuild.
Another OZ MZ being resurrected.
Parts postage can be a bit steep from overseas, but thankfully the parts themselves are nice and cheap :)

I've only used MZ-B in Hungary.
Postage is surprisingly quick, as in I expected about a month but received things around 2 weeks if not sooner.
I needed a whole new crank, exhaust system, piston, plus a lot of littler bits and pieces.

Great project!
You'll need quite a few parts (import duties & taxes?), and with enough tlc you can turn it into a nice bike.

Best of luck & enjoy making it your bike!

its real sad bikes get this bad looking before some one fixes them..

but i can see how it happens as one gets older things just do not seem to get worked on

i have 2 bikes and 3 ham radio transceivers that need work
and all i get done is cook meals and wash dishes and do laundry

Looks like you have lots of work ahead of you. I am in Sydney and am riding an 85 model which I have owned since new. I might be able to help if you have any questions. There are not many of these in Australia. Bruce

With the back wheel out of the bike and enough parts missing to make it impossible for me to unload it myself and hide it in the back of the garage I was faced with the uncomfortable task breaking the news of another bike purchase to my wife. After the initial negotiations and my explanation of the historical significance of the machine , she sighed acceptance. Later we scrutinized the bike together ; she and said it was a mess and that I'd probably have to replace everything.

The more I disassembled , the more I was inclined to agree .

I took the motor out and cleaned it up a bit, but I am afraid that water has got right through the engine

I got the cylinder off last night after some bashing and it seems that the crank shaft is rusted as well *[cash register sound], but the bore didn't appear to be too bad at first glance. I didn't examine it very closely because I had just struck the back of my hand with a mallet on the second to last blow freeing the piston from the cylinder. I thought it was a bit of karma as I had never dealt with a motor so roughly before. Anyway I decided to call it a night and returned upstairs to bathe and ice my swollen hand and ponder how to get the rotor off the crankshaft

To remove the rotor you need to take off the contact cam and turn a M10 screw into the rotor until it it comes off..

Yes . The problem is rust. I have to clean the rusted thread sufficient to get the M 10 bolt deep enough to contact the end of the crankshaft.
At this time I can only scew in about 15mm. I need to get in about another 20mm
