Jaime Posted May 27, 2020 Report Share Posted May 27, 2020 Hello there, I recently bought a Bultaco cross motorcycle 1970 Sherpa S model. It has three wires running out of the engine left cover and it goes directly to a red box which I assume is the starting coil because it goes to the spark plug cap. So here it goes, my question is if I can install a headlight and a back light without modifying anything inside the engine. I thank you in advance for any reply, Jaime.

feetupfun Posted May 27, 2020 Report Share Posted May 27, 2020 If it has the original setup inside the magneto cover, probably not, but you would have to remove the magneto cover to have a look to know if it is original and to know if it has a lighting coil. Another thing you could do, to help people help you, is to mention what digits the engine number starts with so the motor can be better identified.

johnjsy Posted May 27, 2020 Report Share Posted May 27, 2020 No, Jaime. The Sherpa S was an out and out competition model. You could fit a points plate and flywheel from say a Lobito or Alpina to get lights. Your best bet is to contact Lynn and Dorothy Mobley across in Minden Nevada. They handle a lot of secondhand Bultaco Spares, and can give you best advice on this. What is your intended use ? If for off road an Alpina would be far better I reckon. 1 Quote Link to comment Share on other sites More sharing options...
Jaime Posted May 28, 2020 Author Report Share Posted May 28, 2020 Thanks a lot for your reply Mr. Johnjsy, I will try to contact these friendly couple in Nevada. In the meantime I will continue riding it while I am restoring the little beauty. Have a great day! Quote Link to comment Share on other sites More sharing options...

Thanks a lot for your help Feetupfun I will post up the series number later. And if I take the magneto cover, I am looking for two coils or how should I know if it has a light coil? Thanks again!

Yes, you would need to find a stator coil in there that is not part of your ignition system. Quote Link to comment Share on other sites More sharing options...

Hi your Sherpa s has femsatronic electronic ignition , no points , condenser , lighting coils or any serviceable parts . if you want to run lights you will need a complete points ignition or a femsatronic off a lobito .From what I can tell its a 100cc Sherpa s and on some of those the crankshaft taper was a smaller size to the bigger engines so be aware of what you may purchase .Easiest way is to give Lynn mobley a call as he will point you in the right direction Quote Link to comment Share on other sites More sharing options...
