hi all the 199B dose it have a difrant magneto than the 199A? i had the cover of and noticed its not threaded to take the magneto puller. its got motoplate writen on the magneto where these standard on the 199Bs? looking through the slots on the magneto the coils looks difrant to the 199A i can take a photo if needed.

There where two different magneto types mounted to the Bultaco Sherpas.

Some magnetos came from Femsa some from Motoplat, the later Bultacos

which where build outside Bultaco at the Derbi facilities came with all kinds

of magnetos as these bikes where build from the remaining spare parts.

A picture would ineed be very helpful.

Here a picture of the Motoplat magneto that should be mounted

to the Sherpa or Alpina:

hi patrick looks like the sme coil not sure about the magneto cant remeber i will take a photo tomorrow and post it. best regards chris.

hello patrick ive took a photo and it looks the same hear is the magneto

Looks slightly different but shoud be the same as just the center is a little bit different in geometry.

The other model mounted to the Sherpa is the Femsa, (on the upper left, slighty lighter):

Forgot to mention:

The threads should be situated in the rear as seen here,

when you unscrew the nut you will see them.

You need a long extractor for this magneto.

You find them f. e. here, or maybe from Bultaco UK:

I would measure the diameter and the threads of the magneto and of course the shaft lenghts sticking out bevor in forehand and give the spec's with the order just to make clear the Extractor will fit.

thanks i will buy a puller for it. i do have 1 but its for the 199A cheers patrick.
