Best Electronic Ignition

Post by johnu »

I did try the search but didn't come up with anything definitive! I am looking for the best option electronic ignition to use on an mxer with no battery. I hear the electrex is pretty good. Thoughts please :grin:

I just mounted an Electrex on my B25. Pretty sweet. Spinning the engine over by hand with no plug makes a pretty significant spark. It's basically a PVL style and you cant beat it for the price.
No charging system, but if your setting up an MX'r, this is the ticket, IMHO.

Thanks Shawn. You are the second person to recommend the Electrex so i will likely go with that. Is it simple to install and set up? Also where did you purchase it from. I see you are in SoCal as I am (Redlands).

The local VMX crowd are all running Runtronics ignitions which come in single & twin plug variants.
Not a simple plug & play as they will require some setting up.17 hours run time from 5 C cells that will happily fit inside the primary chain case where the stator used to go , you will have to make up a mounting plate.
It is a solid state amplifier so no external coil .
Mechanically tuneable directly off the crankshaft so no 1/2 time gear problems.

I got it from Peter Quick at BSA Unit Singles. It really is easy to install. All you need to do is find actual TDC using a piston stop which is easy enough.

If you need a hand, I could help you out. I'm in Anaheim Hills. Basically the 91 and Imperial Hwy.

The hardest part was getting the grommet back through the hole in the case with the wires in it LOL...I mounted the coil on the bracket were there the old electrical box was using a short piece of 3/4 wide, 1/8th thick aluminum. It's got two wires...kinda hard to screw that up LOL... :ok

Now I'm curious.

Why the dislike of the Electrex? You're the second or third person I've seen try to steer someone away from the Electrex unit.

Why marry yourself to another magnetic pick up (assuming that's the route) wedged into the points case, a capacitor and an ignition box and a regulator/rectifier and the alternator?

The actual timing off the cam isn't more accurate than a crank trigger...in which the Electrex is, unless you simply dont trust the Electrex ignition curve. And being a "magneto" type, the spark gets stronger the faster the engine spins, as opposed to a point style (including a mag sensor) Kettering type ignition system.

I understand electronics quite well. I was a radar tech at Hughes Aircraft for over a decade and I taught automotive electronics for a brief while, so don't be afraid of talking over my head.

This is a genuine question, not a personal attack. I assume you know something I dont.

So with the electrex I assume you can do away with the points and cam under the chrome cover on the right side of the engine.

Technical reasons in favour of one system over another are always interesting, individuals have a plethora of reasons why they prefer one system over another, these will include price, performance ease of fitting and adjustment, weight etc etc. Some will be able to express their opinions eloquently and some can't be arsed to spend time on a forum and would rather be fettling or riding their bikes. These are such versatile bikes, they are made to go fast, to be efficient, to be work horses and record breakers. There is no one best way of doing anything.

The written word can be very blunt and misunderstandings can easily occur especially if English isn't your native tongue.
The moderator always reads everything, and can out pi$$ anyone (except Rickard that is!).


All that said, I run standard points, Trispark, Volker Sachs with variable curve and an Interspan on various road bikes, they all work great.

With Electrex certainly remove the points assembly,not the cam itself though! if I remember correctly (been a few years since I did mine) you have to screw a bolt into the end of the cam to replace the fitting of the points, like a blanking plug, stick a bit of thread sealant on it to help keep everything oil tight.

I just took out the points. Left Everything else. Made a plug for wire.

You left the A/R mechanism in situ? Take it out and replace the bolt, it will only rust up and/or wear out.

Sorry for the confusion.
Got the wrong "tronics"
Podtronics is of course a regulator rectifier made originally by Bob Keiser
Runtronics is a solid state amplified electronic ignition system that does not use an external coil .
In fact you can fit the whole unit inside an old coil case.
We were going to put them on the market like that decades go.
And yes it is a crank timed ignition .
Rode a B44 fitted with one and it did make a big difference to the performance
However it did require a bit of reworking of the carb
Whole thing, including batteries fitted inside the primary replacing the alternator.

The B44 got about 20 hours of running from a single charge
The original T 100 was only good for 17 hours .
BAsically it s hall effect trigger hooked up to an amplifier and the high voltage is then passed through a small step up coil the size of a cotton reel totally enclosed.
It throws cluster spark so there is never a missed engine cycle .

I have nothing against the electrix and if the poster wanted a plug & play unit I would not have posted but he askd for the best & I believe this to be the best, Stan was not a big fan so if you search for Runtronics it should bring the posts up.
On that story any one heard from Stan reciently ?

Hello ,

in 2012 , '' scootin newton'' asked for the Sachse ZDG3 electronic ignition .

the discussion was hot.
Minetymenace used it on a Moto Guzzi , but no one on a B50.

since , has anyone used a Sachse ZDG3 electronic ignition on a B50 with good vibrations ?

it interest me because my outer case has been machined to repair the pillar bolts threads and the ZDG3 stator has no centering
on the background of the case. The other ones have often two magnets that have to be centered i think for a good work.

Pretty sure the ZDG3 for singles has only one magnet. The distance between the magnet and the Hall effect sensor needs to be controlled and circuit board that the sensor is mounted on is designed to fit in place of the points back plate and is centred by the timing side case. If the pillar mounting holes are not in the right place following a repair, you may find that the slots in the new PCB will not line up.

It is probably best to get the mounting holes sorted and in the right place before trying to force a €300 ignition system into a badly repaired case!

Thanks for your advises ,

I phone to AGEX this morning.

The ZDG3 has changed . It uses magnetic sensor now.
The website is old for BSA 's one, i use a ducati 's picture that is nearly the same.
Ducati single ( like BSA B50 ...)
Ducati single ( like BSA B50 ...)
i think the stator can be centered around the rotor with the gaps we can see.

it seems to be very close from the Trispark about performances , but if someone has tested it ?

PES make something similar

May need a new mainshaft, my NEB clutch is on a splined rather than tapered mainshaft. PES available in for both splined and tapered.

£400 - £500 (good old Great British pounds not USD)

Probably going to shave these posts off to "Parts Wanted" in a bit as they are <910 ....

Yes its a NEB as said before.
I think it is also available with taper or spline
