Hello all

Well my daughter is in Australia so it’s been a chance to finally put the high bars on the TS125. They look great and it handles better. I also did the painful task of fitting a new chain cover.

So Eva’s bike was registered in August 1984. When can I apply for it to be a historic vehicle. It’s MOT sadly runs out July 2024 so it may need one more ?

Hi everyone,

First the good news – my 251 is Ulez compliant (£175 less in my pocket though)

The less good is that the substituted Japanese carburettor with which said Ulez compliance was obtained appeared good to start with but has become problematic – in fact it became very difficult to get a stable tick over and smoked more than MZs usually do!

My solution is going back to the drawing board and renovating the original  BVF 30- N- 3-1 carb using a supposedly identically one I had tried earlier but which is inferior overall in metal quality and fit.

My question is about whether a) the pilot air screw absolutely needs an o- ring as neither the original, nor the ‘not so cheap’  “identical” substitute had one. Also there seems lots of different views about turns out for both the pilot and the bypass air screws – any thoughts on this are very welcome. The 251 has done about 32k since new in 1990.

Hopefully if all sorted and passes MOT I may see some of you at the ACE cafe for Red Oktober meet on 13th October.

So my daughters TS125 is going a treat, all good. I seem to have obtained a ETZ251. Its a runner but needs a tidy up. Why are the speedo and tacho instruments square ? sadly they are damaged so I am after another pair if anyone can help.

Also when draining the gearbox oil there seems to be 2 drainplugs. One classically is super tight and has silicone around it. I undone the other which had gearbox oil drain from it but it was the neutral plug, it had a spring and ball bearing sitting on the top!. Should this be undone to drain the gearbox oil.

Any help with this project is greatly appreciated.

Has anyone out there ever fitted a TS250/1 engine in to a B175 Bantam?  Is this possible ?

I understand that the 125/150 engines can be fitted.

cheers

Well many thanks for the info on setting the timing guys. I finally got a decent piece of kit from Burwins and away we go.

I set the points first.  Then got the piston to TDC . The cheap test lamp pen currently blow it’s bulb twice….dont buy cheap on eBay. I carried on and set it back 3mm. I could see the spark at the moment the points open. I reckon I was about 2.6mm from TDC.

It starts well and feels responsive.

Hi all

Has anyone converted there TS125 front brake to a Twin Leading shoe set up ? any suggestions on a good TLS if it is possible. The front brake is poor .

Hello all

I have had ongoing difficulties with the TS125 Alpine carb. If you slowly roll the revs on its fine but a little more  harsh throttle and it goes flat and judders.  I’m keen to try another carb. I think it may just be old.

I’m sure it’s a fuel thing. Funny enough it’s starts and if you lean it on the side stand and wack through the years with the back wheel up its really spot on.

Maybe I’m just too big !

What would be a good alternative ? I’ve emailed Amal to see what they say.

Hello all

Recently the TS has been a real pain to start. ive taken the carbs to bits and its starting a little easier but still taking alot of kicks to fire up. Is it the cold weather , does anyone else have this problem. I was wondering if the timing was a bit out. I did this by ear originally and it started ok. Whats peoples opnion on this ?

Morning guy’s

Currently it’s -4 out there so cant see me going far today. I’ve bought a 6v battery charger with trickle charge system. I plan to just put it on with the battery still on the bike and not disconnected.  Will this be okay or do I risk damaging coils and other electrical units ?

Does anyone else keep there 6 volt battery in situ.

Regards

Graham
