Haha, true.
But the main reason to stop when it snows is because of other vehicles on the road. Even if I manage to stay on two wheels there are some vehicles with 4 wheels which have some difficulties to come to a halt when they should, or stay in lane...
But I might get myself an extra pair of wheels with spikes just for the fun of it and use it on lakes or offroad where there are no other traffic.

The main reason I don't ride in the snow (anymore) is I have become a fair weather biker, too hot or too cold, not for me (anymore)... I like my creature comforts too much I guess. I've put in my share of cold and hot rides though. I'm gettin' too old for the really rough stuff...

I never stop riding, winter is fun and special!!! Use spikes, with screws you never know when they are gone...I ride Trelleborg, but why are we talking winter in summertime Enjoy summer

I agree Xtrock, lets enjoy the summer.
By the way I'm going to Geiranger, Trollstigen and Atlanthavsvejen in August. Not by XT but with my Virago. Hopefully there will not be that much of rain during the trip.

A pic from Nov 2010. Guess what is under the pyjamas. Yep, the blue one. That is how it spends the winter. The other one is on its way to the garage.

Oh thats a extreme nice trip, they had a nice summer so far. But when it rains its not for a day...hope sun stays with you

Hi again,

Seems like the bike has been involved in some serious breakdown in its earlier life.
One of the bolts that is holding the pick up is broken and it looks like they have tried to drill it out but failed.
The pick up seems to be pretty solid with just one bolt anyway so it is not like it is rattling around.
It seems like the distance is not possible to adjust anyway because the holes in the pick up are punched and they fit very tight in the holes in the cover.
I will try to drill out the bolt and make new threads.

I did some more measuring of the pick up itself, which I'm not so sure if it tells anything. But here it comes.

Measuring between the two pickups= 11 kohm
Measuring between upper pick up and ground= 6,5 kohm
Measuring between lower pick up and ground= 4.5 kohm

Red/white to ground= nothing
Green/white to ground= nothing
Green to ground= nothing

No connectivity to ground via the wires.

Any suggestions where to find a pick up ?

Have you measured between the wires of the pickup. They are connected to ground in any way, in fact if you did measure between any wire and would indicated a short.

Measure between all combinations of the 3 wires. White/Red to green 110 ohms, White/Green to Green 110 ohms, White/Green to White/Red 220 ohms.

Oh, I looked back and see you measured this already 110 117 ohms, not exact. Look for broken wires on the coils.

Hi Steve,
Nope, no loose wires to be seen.
Did some new measuring with another Multimeter
Brown between Red 158 ohm

Trigger measurement:
Green between Red/white 117,3 ohm
Green between Green/white 116,5 ohm

Green/white between Red/white 232 ohm
Measuring between the two pickups= 9,87 kohm
Measuring between upper pick up and ground= 5,64 kohm
Measuring between lower pick up and ground= 3,92 kohm

What I don’t understand is why there is no reading between wire and pick up itself, in my simple world it should be. And why is there connectivity to ground from the pickups ?
You don’t need to give the full explanation, just tell me if this is OK.

I do have a different color scheme but what I have discovered is following.
Green = my black/yellow
Red/white = my blue/yellow
Green/white= my Green/white

I have discovered following (I stick to your color scheme) Red/white is somehow in connection to lower pick up and Green/white to upper pick up.
I discovered that with following test:
Measure between Red/white and Green and move a hammer over lower pick up the ohm fluctuate between 117 and 125 ohm.

Measure Green/white and green, move the hammer over the upper pickup and the reading will fluctuate between 116 and 122 ohm.

Does this give you any idea ? To me it indicates that there are some life in the coils and magnets. But maybe the readings should be different.

Tried to search for another pickup on the net but it seems not to be that very common. Any ideas where any spare one could be found.

Just from my experience the pick up and CDI both are fairly reliable and not usually what's wrong. In the past I've put an oscilloscope on the pick up coil to look at the waveform but it's tiny, I don't think you'll measure anything worthwhile with a multimeter other than its resistance. I'm fairly sure the CDI needs a good earth on one of the pins, can't remember which one. If it's not present you'll not get a spark.
It's a long shot but I remember once having a plug cap with a very high resistance. If it's like mine you can unscrew the brass clip that attaches to the spark plug from inside the cap to reveal the resistor, clean it up with emery and reassemble. You'll find the resistance back to where it should be.
Sorry can't be of much more help, but like one of the other guys I too have had many broken and bad connections over the years to the point where I tore off the loom and made up a new one myself.

Your measurements are correct, the coils are isolated from any ground connection. The metal part of the coils is how the magnetic fields are fed into the coils. Magnetic fields crossing coils induces voltage. The voltage generated is AC (Alternating current) and IS measureable with an AC voltmeter. I've done it. It is not very important what you read as long as you see the meter Kick, I expect you will see the voltage as the coils are working.

If you can borrow a coil and a CDI unit you can see which one is bad. I suspect the CDI unit. I've had two of them bad and all the ohms and voltage kicks checked out like yours. Both of my CDI's were bad. 30 years is a long time and they are dying all over the place.

If you want suggestions for a replacement CDI, just ask, just DO NOT BUY a used one on eBay. Why buy another that is old, they go bad due to age, not miles.

Steve
