starting my build this week already have the motor in....however i bought just a motor for the swap not a complete bike,so i would like to use the stock T3 wiring,i assume that all the electronics will work except the head light and tail lights,basically i need to know were the wires off the KX stator should go in relation the the T3 harness wires

Are you using an 84-85 or 86-87 Tecate?

here is the wiring diagram of the 86 tecate.

Do you have the cdi of the kx 500? I dont thing that the kx 500 will work with the tecate cdi.

I have also fotos of the wires on the 86 tecate to see where they go if you like them let me know

Post and some pictures of you project if you like :)

ill post pics as i go along,that drawing wont go larger for me,any ideas?i have to look through my parts to see if he sent me the 500 cdi,although im not sure why the tecate cdi wouldnt be able to fire of the coil as long as the wiring is correct they are both the same voltage system and accomplish the same function

thanks,anyone have the kx500 wiring diagrams?

You need to use the kx500 cdi if you are using the kx500 stator/flywheel setup. The tecate and kx500 cdi's have completely different timing curves from eachother. Engine damage and poor running would likely happen. Also the kx500 stator does not have a lighting coil to power the stock tecate lights, but you can buy aftermarket lighting coils that bolt right on the stock kx500 stator plate with no mods for around $70. A clymer manual has a very detailed wiring diagram on the kx500's.

What year is the KX500??

i was aware of the lighting,that doesnt concern me right now,do you know if i could use any cdi fromany year kx or does it have to be from 89 and up?i cat remember if he sent the cdi or not.....ill check when i get down to the shop on minday,if not does nayone know wher i can get one,i already searched e-bay and all of them on there are 85/6 &7

A cdi from a 90 and newer k5 is what you want to have. 87-89 cdi's were the same, in 89 some models had the older style cdi on them and some of the later 89's had the newer current style cdi. To be sure I would just get a 90 and newer one.

do yu know of hane if the kx250 cdi's of the same year were interchangeable with the 500's?im assuming not but ya never know

I proposed some theories on this but they are more like guesses based on what i have read on other posts. See my thoughts here about KX500 and 250 electrical systems:

seems like a logical theroy,i just wonder if anyone has ever done it,so do you think that the kx250 uses the same timing curves as the 500's?

i posted the links where the KX500 owners used both KX250 and KX125 electrical systems. Yes the timing curves are likely different as i know they are between a LT500R and LT250R. But this does not change the fact people successfully used other complete electrical systems on the KX500.

You are asking to mix the KXT250 CDI with the KX500 stator and flywheel, most people dont mix these parts but you are welcome to try.

The stator output and possibly the flywheel from 1986 KX500 was the same as 1986 KXT250.

no i was thinking of mixing KX250 cdi and harness with the kx500,of coarse this is only if he didnt send me the kx5 cdi,which he may have.......im just trying to get my ducks in a row in case i need some parts,i hope to have this pretty much finished up bt the end of the week,so i dont wangt to be doing all this research at the last minute

well ijust located a harness and a good cdi box for $60 so im just gonna get that,it would be a good idea to have a good extra even if i have one already

to me the stator and flywheel will just produce the current and the CDI will time it, but here is the problem I see with that: how will you set the timing? the mark on the stator is for KX500, the spark will fire at timing for KX250, using degree wheel and TDC will put you where?

thats the part i wasnt sure of either?

Timing is something I wouldnt play around with unless you have lots of time to tinker and knowledge of setup. Yes there are people that have put complete kx250 ignitions on Kx500's but you will need degree wheel and timing light. And alot of times you never hear a long term ride report to conclude if it was a true success or not. Too much advance, not enough retard and vice versa on different models ignitions make for extreme savvy tuning, sure it can be done but for the safest and best situation right from the start would be what the Kawasaki engineers did the work for us already with the original K5 ignition.

The original KX500 ignition is the way to go and the easiest. The guy who built the fastest KX500 in the world swears by the OEM ignition parts for the average user.

I agree, plus it will be easier starting and you can add a lighting coil no problem when the time comes.
