Hiya,
Thanks for your fast reply.
I am Gibraltar, Southern Europe.
The mechanic who rebuilt the engine commented that there was a problem with the oil pump for NS125's of my age. Something about a bit being metal and not nylon..
Anyway the bike started makeing a loud whirring noise and after 5 k's it cut out. I was in Spain at the time so I got an spanish scooter workshop to pick it up and sort it. Prob is that the idiot spanish mechanic did'nt clean out the metal fileings etc. So after another 20'ks the engine ate itself.
This time i was in Gibraltar so a good mechanic (a german by the name of klaus of all things) fixed it. I was a bit wary of the bike so I sold it within a few weeks.
Now I look at one that is going quite cheap.
Cheers
