Unfortunately photobucket have decided to change their Ts&Cs so my pics are no longer showing unless I pay.

But my post that I started a while ago is here when I was rebuilding my CB125T2. It's still not finished & even less likely to get done anytime soon as i'm going to be a grandad in February & my efforts & spare time are being used in a different direction atm.

For those who are wondering about the back end looking out of place, and i'm one of em, i'm removing the rear sissy bar (if that's what it's called), and shortening the inner black mudguard. I'll then need to do a bit of welding for the seat to fit correctly. Watch this space cos i'm no welder but i'll give it a go.

If you leave the bar on the back Pete you could place one foot on it and pull amazing wheelies, just sayin 😗

Ha, I wouldn’t dare try one nowadays, mainly because I’ve seen others do it and fail, and there’s definitely no more effective way of making yourself look a complete plonker!.

Now got the engine in and handlebars on so I've ditched the broom handle.
I'm still looking for any information regarding placement of the condensers. On other bikes i've had/got, they were placed underneath the points but not on this bike. The schematic shows it up near the battery housing but if any one anything more specific with photos that would be a great help. Thanks

Hi, so I've  got the condenser sighting sorted and I'm on with the electrics. As I mentioned earlier, electrics are not my strong point. I have got power to the points (Tested with a circuit tester bulb) but no spark at the plugs. Any ideas anyone. Cheers

You can look at the points as a switch to earth,  so when they are open the earth is disconnected.

If you supply a bulb from batt + and earth through the points it should be alight with points closed and go off as points open.

One of the most common problems is with the little insulating washers where the leads connect to the points,  if not in the right place then the lead is earthed all the time and gives no switching.  So obviously no sparks.

Nice work on it,  bike looks really good.

On a similar note, there should be 12V on one side of the coil and a fluctuating 12V (12. 0. 12. 0  12........)    on the others side, caused by the points opening and closing.   This can be checked while turning the engine by hand.
Where's that 10mm socket got to?

Hi, thanks for the replys. I do have power to the points and when doing the timing, the bulb from the test light goes out and comes on as it should when the the crank is turned. As for the 12v mentioned, the coils are 6v. Cheers
