MOT exempt?

2 Replies

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 ?

High beam a no go!

8 Replies

Hello all again.

Well good news. My daughter passed her Mod 2 on the TS125. It’s been very well behaved then we went to Lithuania for a week leaving my daughter at home (18 and we were expecting complaints party wise!) and while away the TS played up.

Headlight bulbs blowing , but we have now  got to the stage that dipped is fine but as soon as you switch it onto high beam it blows. Can anyone tell me the correct wiring colour for the 3 wires going into the bulb holder,from left to right. The parking light is odd as it only works once the headlight shell is on, maybe it needs to earth. The annoying thing is the wiring looks great and has be redone a few years ago. I’ve got to say though the wiring going into the right hand switch is a pig to get in and get the cover on with the runner mat in place as well.

Any help always appreciated.

MZ 251 clutch

2 Replies

Hi all

So I’ve started to play about with the new addition a MZ251. I noticed that the clutch is not fully engaged when the bike is in gear.

So I’ve adjusted the clutch and done the 11mm distance from centre of the clutch cable nipple to casing. It was still the same the clutch when pulled in not fully engaged.

So should I increase the distance of the clutch rod which the cable goes in, or should I reduce to less than 11mm. Another problem is when you do this the plate which sits on the part you adjust does then not line up to allow you to do up the 3 allen bolts to out the round casing cover back on. Does this make sense to anyone ?

Regards

New MZ !

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.

Timing set TS125

Leave a reply

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.

Help Carb advice needed

Leave a reply

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.

Trickle charging my 6 volt ts125

2 Replies

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.

Air inlet pipe frustration

2 Replies

Morning all

 

So I bought a new air inlet pipe. The last one never really sat on the carb well so I figured it was worn and old. Got a new one through and I currently have this Laurel and Hardy situation that every time I try to put it on the carb it pops off the panel with the air filter. Any suggestions as currently its on the carb but not completely seated in the other end. Though looking at the plug I do seem to have a nice biscuit brown colour !

OMG ive fixed it

Leave a reply

Hi all

Well after lots of different attempts to stop the indicators on the TS125 flashing erratically. Its fixed.

I bought a 6v indicator relay from M and P motorcycles. Different wattage and it works. The only thing is with the engine off the indicator warning light stays on all the time when you try the indicators with the engine off. With the engine running it works fine and at high revs the indicators stay constant. This may mean that there is an issue with genuine flasher relays.
