Xt 600 tenere wont start
 
Hy there all.

So I sold my xt600e a couple weeks ago, and now I found an older xt 600z tenere, supposed to be 1989, not sure. It has no documents...

It was cheap, and I got an extra engine with broken gearbox, to go :)

The seller said it ran last year, but he was messing something with the electrics. Anyway it doesnt start. There are 5 wires coming from stator/pickup coil, the red and brown are for cdi power, but I am not sure how to connect the other 3, there are no connectors either on the cdi or the wires from stator, everything is cut off and then just twisted together. I get the spark, but Im not sure if the timing of the spark is correct, the engine sometimes pops from the exhaust, but doesnt start.

It has an e-start, and later added kick start.

Hi
Download xt 's service manual (pinned at the top of this section) and find the page where wiring diagram is shown and explained.
If there's any big difference between xt 's and tenere's electronics, I suppose it will be easy to identify.
Otherwise, that manual should help. Sorry can't tell exact page, posting from my nav device, on the way

Thanks, I already have an xt600E manual, but the electrics are not the same. Im still strugling to get any info on the specs for testing the stator, ignition coil, pickup coil, cdi. Im also not sure if the compression is within the limits, I have a gauge, but I dont have the 12mm coupling to bolt in to the spark plug thread. But my friend has a 2kf xt, and kicking it is almoast identical. I poured some gasoline down into the barrel, put the spark plug back in and kicked it, but nothing happens, not even a pop. I think the spark is too week, how to tell if spark is good???

Curious about a few things:
  1. Can you get an engine/vin nr? Can possibly trace the year with that.
  2. What exactly are you looking for from the Tenere manual - I have one for mine. but not sure what the last year is- I'll need to go scratch for it in the shed
  3. When you say electric start, but kick starter added- do you mean it was originally e-start and converted afterwards? The 86 model had both e-start and kickstarter- so could the motor be off an 86?

Happy to try and assist, just need a place to start.

Not sure, could be 86, I will post vin nr. tomorrow.

I got the manual, and all the electrics chek out fine, according to the manual, but I couldnt find out wich wires from pickup coil connect to the cdi, as they are not same collors and have no connectors. I searched through google, but some say different than the others :thumbdown:

I took apart the carb once again, to clean it good. I will know more when I compare some parts from a friends bike, although he has an 88xt600, but should be very similar.

Btw, I have an extra engine, with broken gearbox and a good top end for sale. But there are some parts missing.

No rush form my side... If you're not in a rush, I'll have a look at my 86 on the weekend and take some photos if that will help.

Unfortunately, the bike is at the back fo the shed and I need to get everything out before I'd be able to get to it and the light is not that good in there (for pictures)

lslabe 20 Jun 2017 19:31

No problem, really appreciate your help though :)

I will be working on the bike again on weekend i guess, too busy at work...

But any other thoughts would be very much appreciated.

lslabe 20 Jun 2017 19:34

Btw, how come she's at the back of the shed? You should be out there riding it. Dont know where you are from, but we got 30+ degrees here in Slovenia ;)

Squily 21 Jun 2017 12:42

LOL - no, she's a project bike. My 1st 'adventure' bike was an 86, so they have a soft spot for me. That specific bike is still running and now has well over 200kkm on it.

This bike belonged to a mate (and was his 1st adventure bike). When he wanted to get rid of it, it came here out of nostalgia. She's running, but not what I want it to look like etc. When I get around to it... Maybe a side-car conversion...

In the mean time, I'm enjoying my new AT :innocent:

Squily 24 Jun 2017 23:02

Now I'm confused as well!!! LOL, I looked at the wiring diagram in my manual, and none of the colours match up either. Can you please photograph what you are looking for, and I'll go strip down and do the same.

Sad part on my side- chucked some fuel in the beast and she did not start either. Motor turned over bad very 'badly'- sounds like something is wrong in the engine so I'll have to open her up- maybe even some rust in the sleeves :(

These bikes take a certain amount of volts for the ignition to allow spark plus the motor needs to spin over fast enough . A weak battery may seem fine but when cranking the motor over it goes below the cutoff voltage (11.2V IIRC) so they won't spark, hence start. Something to check first.

lslabe 26 Jun 2017 07:43

I will take some photos today and post them here. Still have to clean and reassemble the carbs tho.

True, but when/if you use the kick-starter it should not have an effect. I used my bike with a blown alternator coil and dead battery for a few weeks and thousands of kms with just the kickstarter.

So I got the carbs cleaned reeeeeeal good.

Bolted everything back to the bike, bypassed the fuel pump just in case and then crancked it a few minutes. Nothing! So I took out the spark plug and it was bone dry:thumbdown:

I get fuel inside the carb, but I am still missing something.

I probably done at least 50 bike and car engines, but this one giving me the hardest time ever:censored::censored::censored:

One more thing, I took the air filter off, but i guess this shouldnt be a problem right?
