I prefer the TS250s to the ETZs (250 or 251) - less peaky power delivery & more economical, but the disadvantages of 6v electrics and drum brakes. I had one of the last DDR-era produced ETZ251s, (in a fetching shade of beige) rescued from my brother-in-law, who had bought it new but then lost interest & left it festering in a damp garage. Build quality had rather gone down hill by the end of the DDR, though. Didn't keep it long, though did do a round trip to the Ace Cafe for the first "Red October" East European bike day on it - near 400 miles in the day & a long way to go for an expensive, indifferent burger !

My late friend Mark Dicker was Classics Officer for the MZ Riders Club & he reckoned that the ETZs would disappear before the earlier bikes due to frame corrosion - the area of the frame that the footrest bar bolts to rots off. The frame is used as part of the inlet air system & heavier dust accumulates at the bottom of the frame - this gets & stays damp, causing the frame to corrode from inside. The TSs used a similar intake system, but the tubular frames were heavier gauge than the sheet steel box section on the ETZs, so they last better + the tube is blanked off with an easily removed plastic plug that enables the dust to be cleaned out. The ETZs have (IIRC - it has been a while) a welded on closure with a small, easily blocked, drain hole. May be worth checking this area on your tidy bike ?

I have 6 in various states of assembly & function - 3 off TS250/1, and ES250/2, an ES150/1 and an ETS250 G5 ISDT Replica , of which only the oldest TS250/1 (which I have owned for 29 years) is running. So many projects - so little time !

Hello Nigel

I have given away worlds best turning Boxford to a friend ,thrown a lousy Boxford out and given two chinese lathes,WM280 and a WM210 away and mistreat a WM250 for the moment.

Next time I fall in love with another lathe I think we make swap .A Lathe for a MZ?

That dirt collection problem in ETZ frame is new to me and I sold it many years ago.

It reminds me of my four Austin Maxis that all died from rust due to dirt in the front transverse bridge.

Front wheel threw mud into a corner.

Not all two strokes from the 60’s era had to be smoke generators, I had an Ariel Leader 250 two stroke in that era which I ran on Filtrate colloidal graphite as the lubicrant in the fuel, I can’t remember the exact ratio of lubricant to fuel but seem to remember it was 100/1, the exhaust was clean with only a trace of blue smoke. Ah those were the days.

Sorry about double post.

I had the 250 Ariel 'Golden' Arrow in the same era and that ran clean also, without additives. I'll echo your 'Ah, those were the days' !

There are many fools in this world.

Nice to know I am not the only one.

I had a vision on 23 dec 2014 described here

Future car engine?

Some commented nicely and some not so nicely.

Someone in Austria are working on same idea.

Maybe better new car engine

Is it tempting to stop modelling and do some engineering?
