I should probably start off by saying that I would suggest just spending the $85 for the correct Eton CDI. With that being said- here's a way to save yourself $50!

Here's the $85 Eton DC CDI on Ebay. It has the green wire that can be cut to eliminate the RPM restriction.

Here's another for $75.

As you can see the price is a little high which is what prompted me to search for alternatives. I tried a 4t DC CDI but the timing was too far advanced at anything above idle.
I ended up using this DC CDI at Parts For Scooters for $30 which is meant for a 2 stroke Honda Dio. Part # 169-158



It may seem a bit daunting to try to re-wire a CDI to work, but these 2t DC CDI's are surprisingly simple. Although they have 6 pin connectors they only use 4 of them; 12v+, stator, ignition coil, and 12v-.

Here's the Eton wiring diagram:



Here's what mine ended up looking like. I had cut the wires while trying a few different configurations, but if you're using this CDI for your Eton you can use the original plugs. You only need to swap the ignition coil (white/blue) and 12v- (black) pins around.



I thought I should also add a quick tip about the DC CDI here: when I was using the battery that was junk that came with the scoot I experienced very hard starting- when I'd hook the scoot up to a battery charger it'd start on first kick!
I purchased a brand new battery and she now starts right up everytime with no problems.

You da shit Boss. A savings of about sixty bux. To me, that's a big deal. It's actually the difference between having a working bike, and trying to buy a cdi made of unobtainium

Awesome! Glad someone else could make use of the info! My pleasure!

You'll have to swap two of the wires.
Here's where the wires should end up on the DIO CDI:



Here's what mine looked like when I was done. Sorry the pic is so blurry, but you can see where I ended up putting each wire (it only took 4 wires- I think the eton scoot harness has 5 wires coming out and if I remember correctly, I ended up grounding the 5th wire that was leftover to the frame...



EDIT: I edited this pic and rotated it so's it now matches the orientation of the drawing...

[niz76]

Disregard the fact that the stator wire (blue/white) ends up being yellow where it plugs into the CDI- I spliced a wire onto it that had the tiny pin connectors and it just happened to be yellow...
Instead of cutting the wires like I did (there were many many failed attempts at the configuration before I figured it out haha) you should be able to just use a tiny screwdriver or pick or whatever to release the pins from the plug and rearrange them for a nice clean install!

So my original factory cdi only has 4 wires,and you r saying that the wires that need to be swapped are in the 4 pin harness not the to pin harness

Not clear as to what you're asking here? Are you trying to do a Eton beamer to DIO CDI swap also?? 

EDIT: Nevermind this statement. I must've been having a dazed and confuzed moment haha. I put the answer in the next reply... vvvvvvvvvvvvv

OK- I re-read this and now I understand. Yes, the two pin harness stays the same. It's only the wires in the "4 pin harness" that get swapped...

Ok thanks, i will be back Friday when the cdi box comes in. Thanks so much

So after I installed the new cdi and bbk my top speed was only 35 on level ground. After my first tank of gas it froze up on me. I removed the spark plug and it was a grayish color so I'm guessing that it was running lean as hell. I went ahead and removed the head and cylinder, but piston bottom ring was stuck and the piston has scratches on it were the ring was stuck. I found another piston but it only has the top ring,does that matter or not. It's a hoca 47.6 piston, and I still have the stock carb an air box,I'm gonna order the piston, 10pcs jet kit an aftermarket air filter. Any suggestions on these parts?

[Elektrey]

You mean it's missing one ring, or it only has 1 ring instead of 2?

[crutchfieldcreations]

Yes the new piston I found only has the top ring,does it make a difference

[Elektrey]

Lol I'm still not sure exactly what you mean

if it's got a spot for a second ring and there isn't one, don't use it.

some pistons have 1 ring though so if it just is made with one ring its fine. My piston is a single ring piston.
