Hi, i have a Yamaha XT600 43F that I am building for flat tracking with no battery.

I got a CDI from my old TT350 and have tried to use it on the XT600.

Googled around and found that the "ignition advance values" from the different models are almost the same.
TT350 12 degree @1200rpm and 34 degree @5000rpm
XT600 12 degree @1200rpm and 36 degree @4500rpm


I have got it to start, but it runs really bad and with a lot of banging in the exhaust.
It sometimes also kickbacks really hard when I try to find the sweet spot. This has made my friend and me limping around for a week now

Anyone know if this is going to work out or not?
Could it be that I have connected the trigger coil wires wrong?

There is a local guy here that has a used one from a 87 XT600 IVJ but the price is a little stiff, 170€ and I don't know if that one would fit any better.

Cheers

Another forum member Steve Loomis posted this information over at Horizons Unlimited:

"I just installed my new Zeeltronic CDI for the older CDI version XT's. Installation was very straight forward since I had already programmed my advance curve. The unit came programmed but I wanted to faithfully follow the curve in the manual so altered the setting just a bit. 7000 RPM limiter was already set and can be removed if desired. the 250 Minimum RPM for Kickback protection was already set and I left that as well.

The programmable CDI comes with the Stator Plug and the 2 bullet wires going to the Stator already installed. The other, shorter wire loom has the Orange wire female bullet connector for direct plug in to the coil. The other 2 wires is for the Kill function and is Black/white stripe and ground is a solid black and have the correct bullet connectors installed.

The models of XT's without the kickstand switch will plug in directly and only need the 8 wires provided. If your bike has the Kickstand switch there will be a plug to route the neutral light wire through the CDI and an input for the Sidestand switch.

By now many have already bypassed the faulty sidestand switch so it is really not necessary. If this is true for you then you need the basic model and currently the only model ready to purchase. My 86 has the side standstand switch and it was bypassed. I removed the plug close to the CDI location, added the appropriate bullet connectors to match the CDI and plugged it in. Part of the process is to connect the blue wire from the neutral switch to the sky blue wire going to the neutral light. Just plug them together or solder and tape them.

OK, so how does it run??? My seat dyno wants to say much better, but I don't know yet to be honest. The XT has so much power anyway at 1200 feet AMSL it just pulls your arms very hard. Starting is a 1 kick affair if warm. If sitting for a day or two or more, I learned here or another forum to do the following: gas on, key off, no throttle, Kick 3 or 4 times ( I do 3 times) fairly easily, then key on, kick slowly until the compression release clicks, release kicker then kick a full kick and 9 times out of 10 it will start right up. This was true using the Hyperpak unit as well.

As I was enjoying the ride, I reved it till the RPM limit hit. Engine just kind of fluttered and would rev NO higher. I grabbed the next gear and off I went.

There is another loom for optional use, one wire is for a shift light, one for driving an electronic tach and one to go to +12 volts if you want to use the handheld programmer with the engine off. If you use the USB cable and a Laptop, the USB port will power the unit for programming. You most likely will not need the programmer, but I like to "Know" how things are programmed. One last wire is for switching between two programmed advance curves by either grounding or un-grounding the wire via a handlebar mounted switch. You can make your own or buy one from Zeeltronics. His web site has various plugs and pins for crimping your own. Go to www.zeeltronics.com. This unit is not listed yet but an email to Borut will bring you a response to your questions.

I will continue to ride and evaluate this unit and report honestly. So far I am happy.

Steve"

thanks Steve for the write up, I've bought one for my white 1VJ resto mod.
I have the Zeeltronic units on all my RD Power Valves, generally gives a much better start and crisper feel on a YPVS and the added advantage of being able to program the power valve cycle.

Scottie was "Quoting Steve" who was Steve Loomis, who was on here & the HUBB but hasn't posted anywhere for a couple of years now which is a shame as he was our "go to guy" on ignition issues.

Mezo.

Either switched or one of the trigger coils has a problem timing the CDI correctly, I would think. Bad news is that there are no spare pickups available, we are stuck with used parts. They always were part of the stator, shared the same loom. More often these days they give up.

Thanks Scottieh! I´m gonna check out the Zeeltronics!

I have a little hope for the first option so gonna try that as soon as i have sorted the wires out!

Anyone has a wiring scheme for the 43F?

Check the hotlinks section of this forum. There is a black and white 43F wiring diagram in there. Good luck with Zeeltronics. Post back with more info about your process ordering from them!

I ordered a Zeeltronic box recently.
Absolutely no headaches.

Borut is quick replying and his English is excellent. No order fulfilment guy, no hotline or call center, just Mr. Borut on the other end.
After you agree what you need and you ordered via e-mail, he will send payment info. You do a bank transfer, and after 2-3 weeks you get an email that the box has been posted, including tracking info.
I think he builds them to order.

I did order this February:
The PCDI-XT XT600con is about 160 Euro, postage is 15 Euro (EU)
It is the same CDI for all 4V XT600 models, which has no connectors for the newer sensors (Electric start) but only a black-white wire to kill ignition when connected to ground (which is fine for the ignition switch, but not the sidestand switch or kill switch of the 1VJ and later. You will need an extra relais and some thinking there).
I am OK with that as it is my backup to bring me home should the original CDI fail.

Any more questions?

Andy
