Electronic ignition

Can anybody recommend a good EI system for a CB500.

Boyer Bransden every time. Bit of a faff to fit but well worth it. Avoid the cheaper ones as you'll end up at the side of the road scratching your head.

I installed a dyna system and accidentally fried it by leaving the key on for awhile before starting the bike - apparently if you don't start the bike the unit wont discharge and nasty things happen - there is a risk if on for any more than 10 seconds... really wish they would have said that in the manual....

How about the Units that David Silver sells at around £100?

I know Norniron got one from DSS and said it was shite.

Could you be a bit more specific? Cheaper ones of Boyer & Bransden you mean?

Sorry I should have said, stick with Boyer and avoid the cheapies like the dss unit or the other eBay offerings. You only want to do this once so pay a bit more for the Boyer unit. There's people on here that fitted Boyer 30 plus years ago and never touched it since. Highly recommended.

Could you be a bit more specific? Now your comment has much of the 'Now that I've spent all that money, it must be good bias'. What other eBay offerings do you have experience with?
Heck, I've built my own (for less than € 18,-) and it has worked perfectly for 15 years till I tore some wires myself by mistake. I'll repair it soon as all components are still OK. There's nothing special about EI. If you look closely at a contactbreaker it must be more expensive to manufacture  than an EI.

Not correct DeltaRider, I don't care what it costs. Boyer has a reputation in the EI game second to non. This is a topic that has been aired again and again on this forum and on the internet generally and the opinion is usually buy Boyer. The online forums are littered with tales of DynaS failures. Already on this short thread Dyna and the DSS systems have been slated. Just trying to help a forum member as not everyone is capable of building there own.

On a more positive note. The Boyer system not only does away with the points, but the mechanical advancer as well. Thus becoming totally electronic. I have it fitted to two of my bikes, and would definitely recommend them. But Deltarider is absolutely correct in that it is an expensive system especially if you use the matched mini coils as I have done.

Hope some of this has assisted you Masonmart.

To say that the DSS units are crap is a bit of a sweeping statement without saying why. I guess that the main reason is that they use the existing advance and retard?

Just another question. How much improvement does EI make over points? For an engine that hasn't run for 40 years and has just been rebuilt may it be better running it initially on points?

It was indeed Pure SHITE Graham

[Norniron]

Doesnt Hondaman on sohc.net do a electronic ignition for the 500/550 that incorporates the original points?

  can't say better than that,

 it may have gone up since then,but I am very happy with it

Why don't you say it as it is David

Have a look at this link:

Boyer don't actually list a system on their website for the CB500 so unless the 400/750 system fits it may be ruled out. Someone will know?

Cant think of another system other than Boyer that does away with the mechanical advancer.
