Tecate CDI Recreation - For Sale

No dyno access.

Timing light may do it. It hasn't fired yet. I tested it on my lunch break.

I've got more kinks to work out. The zener diode.. May not be even be a zener diode lol.

Within the week, I'll be pulling the cdi donated by Maico part. I want to double check all the capacitor values.

Anyone have a source on boxes that I can put the circuits in? I want these to be able to bolt up. I'd really like it if we could use the bolts to hold the cdi on as a ground. Eliminate 1 wire.

I think you'd be better off sticking to an original design. They were rubber mounted to help isolate from vibration. A solid mounted CDI box is asking for failure. I don't know of any bike/trike/quad or sled that had a solid mounted CDI box.

[RubberSalt]

Your are correct, these machines do put out some good vibes lol.

If anyone sees a possible idea for a box, send me a link. I've been pricing blank circuit boards being custom made. They are only cheap when in bulk. I'm going to try and stick with the oem board with a slight change to the traces to accommodate the changes for new SCR (ec103d).

The first few units I build and send out will be on prototype board.

I'm not sure how many you plan on making, but etching your own boards (especially a single sided board) is not too tough. The process involves exposing a special board sandwiched with your circuits printed on clear film to light, rinsing off the chemical resist that got exposed to light (leaving your traces), and then etching in ferric chloride. You can print multiple CDI boards onto one large board, process the one large board, and then cut out the individual boards using a saw.

I can make a mold of the oem box if your finale board size will be able to fit inside so resins can be poured into the mold thus encapsulating and sealing.
Can copy the oem mounting rubbers as well.

I need to looking into etching the boards and the cost to do so. The copper claded board, the UV light(not sure if sunlight or a blacklight works), an theetxhing solutions.

I wish my 3d printer would have been here already, cases wouldn't be a problem. As for molding the OEM case, we may end up doing that. Same for the connector that goes to the stator.

Woot!! Engine is running off a bread board. After a few tweaking to which capacitors and which diodes are in play, it fired.

[jeswinehart]

That's great ! So you got 2 very cool things going on,,,, building CDI's and a 3 D printer coming ~ nice !
Whats the ETA on the printer ?

I was on rocky mountain atvmc yesterday looking at all the oem replacement parts for an 87 t3 and out of all it says the cdi box ships in 5-10 days. But stator flywheel everything is discontinued. Check if im wrong

[RubberSalt]

No idea on the printer, but they started shipping last month. Many many orders to fill.. Kick starter.

I've got to learn how to use a printer still lol.

I purchased a PCB etching kit today. This will be interesting.

I took the Tecate for a test ride today, in the rain. I taped my breadboard down to the front fender. Kicked it over a couple of times and it fired up. The top end RPM wasn't there, it wouldn't rev.

After a few laps around the yard, it died. Breadboard was wet LOL

Rocky mountain, PartZilla, etc,etc...they all use the factory kawasaki web base as a source for all their parts.

The CDI has looooonnnngggg been discontinued.

I absolutely hate wet bread!! LOL

Nice job,Gabriel!! You're almost there!!

I ordered a bunch of 22nf and 10nf 630v film caps to fine tune the RPM ranges. I also ordered some stackable female headers. It'll let me swap caps at will for testing. There is also a 1/2 Watt 1000 piece resistor kit coming. All resistors should be upgraded to 1/2w. All but 2 were originally 1/4watt.

I received 100 1n5408 diodes. These show a 1 volt drop, can handle 1k volts, and 3 amps continues. I couldn't find the OEM specs, but other schematics show diodes only rated for 1 amp to be used. So I tripled that
