Re: electronic ignition
I done the conversion a couple of times before.

First of all, you have to be sure you've got the correct crank tap type on your engine.
This HAS to be a L-tap, so no taps with a 'flat' Hitachi flywheel fitted.

Next, the only reliable Chinese CDI ignition is the one from the early Jingcheng engines. (DX50, DX90)
This one is plug and play if you buy the special piece of the wire loom. No experience with the Ebay US versions.

It's possible to keep the 6v bulbs and batteries IF you manage to find a correct regulator.
Again, Chinese electronics are far from reliable, and thus I don't recommend them.
If you make the conversion, I'd suggest to do it right.
Get everything running on 12v (regulator, battery, bulbs,...) you won't regret it as it's a big improvement.
(Altough I keep my bike on an oldschool 6v myself)

What you could do is to search and fit in a Honda 6v CDI ignition, as used on f.e. Monkeys from Finland.
Very reliable, very good, but... very rare.

In short: Please don't make a partly conversion. You'll end up with unreliable Chinese parts, weak lights, blowing bulbs, and no-one will understand the adjusted wire loom for future maintenace...

Re: electronic ignition
Well, if you really want the CDI conversion (or fit a fast 6v flywheel), there are 2 options:
1) Replace the crank
2) In some places, you can buy a conversion piece, which slides over the crank tap. This changes your S-tap into the suiteable L-tap.

Oh, by the way, you are welcome! :)

Re: electronic ignition
I converted mine to electronic ignition using a kit off ebay. The guy was in malasia and was very helpfull . It cost about £75 and was quite easy to fit but I had to use the original Honda coil for the lights as the one supplied only had 2 wires coming off it and on UK spec bikes you need 3. I had to email the guy with the reference numbers off my flywheel and the kit arrived about 3 weeks later. You also retain the original Hitachi flywheel. here is a link to the item http://cgi.ebay.co.uk/HONDA-CT70-ATC70- ... 5886693481. Mine has been on the bike about a year and is excellent. Hope this helps.

Re: electronic ignition
Wow! :o
I never heard of such thing!
I guess it's a replica from the old Honda 6v cdi ignition.
Not sure on how it works though... I can't seem to locate the pickup?
And also, the old flywheel isn't equiped to trigger the pickup... Strange...

Yelloperil, are the colors the same as the Honda colors?
Do you had any broken 6v bulbs so far?
And it should work with both L-tap and S-tap cranks?

Thanks!

Re: electronic ignition
Hi Waynus,
The colours on the wires are different to the Honda ones and they have bullet connectors instead of a plug. I made a small lead to fit between the two so I did not have to butcher the original loom.The instructions were great and it fitted perfectly and the bike fired up first kick.I did not use the uprated coil because there was only 2 wires coming of it for the US spec bikes, so I replaced it with my original Honda one.
The guy I bought it off was very helpfull and said he is working on building a uk spec coil. You have to give him the numbers of your flywheel so he can send you the correct unit. Mine works great and I have had no problems with the bulbs blowing.
I have sent a Honda coil to a local company and they are trying to make me an upgraded one to give better ampage for the lighting circuit, if this works I will put it on the bike and let you know how I goes.

Regards
Dom.

Re: electronic ignition
Thanks for the info!

I asked the seller some questions, I will let you know when he answered them.
About S- and L- cranks, advancing flywheels, timing,...
