"4 stroke 50cc cdi" using a ac cdi in place of a dc cdi By donedeal (Read 654 times)

[donedeal]

I've read and read and read about "cdi" ac and dc. My question is I have Kawasaki four stroke 50cc that has a dc cdi  that went bad.I now have a ac cdi that I want to use.is it possible.  (Can I convert my ac cdi to use in place of my dc cdi) its seem that all searches refer to converting a dc cdi to a ac cdi by running a 12v wire to power the dc cdi..any clarification will be appreciated.
Aloha.

it probably could be done by a whole bunch of rewiring, but at that point you might have better spent the $ for a new correct one. as for just plugging it in where the old one was? no it will burn out if you do that.

Thanks for replying.the thing is I have a extra ac cdi for a 50 cc 4 stroke.I got lots of time and the kfx 50 don't seem to have a hole lot of wires.what would need to be done? Do I need to add a r/r? Maybe you are right lantern, that's why I can't find any one else who successfully converted one.again mahalo for your reply and as always if any one has input I'd appreciate it.
Aloha

The difference Is in the stator .

Thanks for clearing that up for me.so I would be converting the bike to ac.

You have it a little backwards , some stators come with a coil to power ac cdi's . The scooters that have dc cdi do not have a power supply coil in the stator to power the cdi , in that case . The cdi gets power from the battery . Your behind the 8ball You started With dc cdi .

I had a scooter that had an ac cdi , It would not start I did not have power from the stator . I then took a dc cdi and plugged in I fed 12vdc to the power wire and was able to get it started .

So your the reverse you do not have a power lead from the stator to power an ac cdi .

Is it possible to run a wire from stator to power the ac cdi? Or would I need to change the stator? Or am i in over my head? Thank you tvnacman for helping me out.something tells me that I should just get a dc cdi.(but where's the fun in that).

[lanternscooter]

you would probably need to change the whole stator if you could find the right one. what engine is this? post a pic?

[tvnacman]

What engine size ?

Need a exact model number, year, etc. It could be possible to find a AC type Kawasaki stator but why would you do this when getting a DC type is easy, cheap and a quick fix?

Only way you will use a AC type CDI is to change the stator if it is DC to start with.

The 2009 Kawasaki KFX 50 sports an air-cooled, four-stroke, single cylinder motor with a displacement of 49.5 cc. A cylinder bore of 39 mm with a stroke of 41.4 mm and a compression ratio of 10.8:1 provides a safer ride for the younger set.
