Best Electronic Ignition System For A '79 199A?

Hi All,

There are a couple of electronic ignition systems available for the Sherpa, but which is best? Has there ever been a test or are they pretty similar?

I would probably opt for a system from Bultaco UK because the guys have been brilliant for parts, help and advice during my rebuild, but what about Rex Caunt?

I've seen systems from the States with lightened flywheels which I think I wouldn't want. Or do I?

I've read comments here which indicate quite a change in engine characteristics, is that accurate? I don't need lighting.

Lots of questions, your thoughts are appreciated.

Many thanks.

Once you change to an electronic ignition you will never go back to points. They start better and run better. I have a Bultaco UK system on my M151 engine and the auto advance in the ignition is brilliant. I can have it as smooth as down low and it will still rev like a 125. I would never go back now and you don`t have to keep timing the ignition. Set it up and never touch it again except to clean the flywheel every now and then. The only thing it has changed on mine is to make it run a lot better. I have a lightened primary drive on mine but that is because I wanted it lighter. If you like the way it is standard keep it that way. The Bultaco UK ones use the standard Femsa flywheel anyway.

sorry to butt in bullylover when you say lightened the primary drive do you mean you have put a lighter weight on it? i was thinking off buying a electric ignition for my 340 but it's running very well on points at the moment. but would like a electric 1 for another bike am going to be doing.

I've got this one on my 350: http://www.francetrialclassic.com/en/ignition/1280-bultaco-trial-electronic-ignition.html

Saves a little over one kg in rotating mass: good, fast enough pick-up but not to light to make the engine stall to easily.

Saves you the work needed to machine off the crankshaft weights on the clutch side, or to buy the crankshaft weights of a 250.

That is a German Powerdynamo, they are really well made and I'am really thinking to get one for my Yamaha.

BTW.:

There is not only one ignition system with light available there is also one without light, even with twin sparks availablke, too different rotor weights.

Not enough you can also get a custom made system: Powerdynamo supplies a lot of brands and I never have heard any complains so far.

Sadly as a reseller France Trial Classic has made some profit to your purchase ... the same iginition from the manufactor would have saved you aroung 50€!
