What Did You Did To Your Motobrick Today ?

[bizzaro]

Yea, my phone will will flip them on the phone as well.  But when I send them, it reverts back.  And it is an  iPhone 4,(old school) so Laitch's link doesn't apply.


I kinda like it.  Nocturnal Alpine Motocross for touring bikes!

Started investigation into cold start issues with the '85 Standard by draining the coolant and removing the radiator to get to the coolant temperature sensor to test. By all indications, it is out of spec. - 4.75k at 20C when I expect 2.5k. Each Pin to body was 1.88. New one on the way from EME and took advantage of the order to pick up some dialectic grease and one of their plastic measuring calipers for a whopping $2.99 just for fun.


I next removed the alternator to replace the rubber nuts. It rattled on startup but quieted down once warm. Did not feel any play in the drive or alternator. I found a mouse nest in the airbox - smelly! Got to take the bottom off to wash it out. Since I had that out, decided to go ahead and replace the Crankcase Vent Hose as it was questionable. Fuel lines look like they were replaced at some point. I did find another cracked rubber cap and replaced it too.


I noticed that the 4 pin connector cover was falling apart but have not found a source for a new one - anyone?

The third reply on this thread http://www.motobrick.com/index.php/topic,10830.msg93715.html#msg93715 mentions one that has been used successfully as far as I know.

Each Pin to body was 1.88.

That is the correct metod to measure it, as it is a double element sensor with common ground.
(one element for the heat management relay, the other for the injection ECU to calculate the mix).

If you have the connector in the front left corner of the tank, you find a unused connector in the relay box
(it's for the factory alarm).

Alabrew have a different connector, unless it's a late -85.

[alabrew]

Build date was Sept '84. I'm not needing the connector, it is the rubber dust cover boot that is falling apart. I looked but did not find if I could just buy it.


This temp. sensor has been a headache. So confusing as to which chart belongs to which bike and how to test each one. I never found what reading I needed for pin to body. Fortunately, the new part is cheap enough to throw a new one in there and job done once.


Looking closer, the fuel line from the rail to the pressure regulator has factory clamps so is probably original. I have the tubing, so might as well change it for piece of mind.

Which connector do we speak about? The only one I remember which have a rubber cover is the
HES Connector under the tank but that is five pin.

You're correct about 2.5K ohm @ 20^oC.

[alabrew]

Interesting. The new sensor tests 4.85 ohm at 20C like the old one. There is no connectivity between the pin to body.


OK, I really don't know how many pins are in the connector, I thought it was the four pin like I read about. Sounds like on this '85, the 4 pin is the connector front left under and into the tank that has a piece of black electrical tape wrapped around it to hold in in. Found it that way and seemed to make sense to put it back together that way.


It is a multi wire connector under the tank. Not too concerned about the cover, but I'm under there and figure it is on there for a reason. Curiously, the open end faces forward but it is jammed up on top of the air box. This is a summer commute bike and only likely to encounter rain on the ride home.

This sensor have no rubber dust boot from factory.

There is no connectivity between the pin to body.

Then you have been given a wrong sensor, do you do like Martin and shop with this guy?........

Building cultural bridges one returned item at a time.  :yes

[alabrew]

Here is the one I ordered: http://www.euromotoelectrics.com/TEMPSENS-K197-p/tempsens-k197.htm which lists for the K589. I think I'll try to test it like described in the K100 Tips of testing at Pin #10 of the FI connector and grounding to see if I get a different reading.


They don't list one for the 89v1 (the K1 and K100 4 valve, and it is still available from BMW), so I don't think I got the wrong one.


I believe the box said it was made in Spain.


The dust cover I was looking for is like this: 61 13 1 459 048 PROTECTION CAP
but at $21...

[Inge K.]

, so I don't think I got the wrong one.

If you don't measure any connectivity from both of the terminals to ground (housing), you haven't got the
correct one.

Would guess it's the one for the HES Connector, it's the only one I know on the bike which look like this.
The one for the power outlet looks similar but is bit shorter, and should be in a different diagram.

[Laitch]

They don't list one for the 89v1 (the K1 and K100 4 valve, and it is still available from BMW), so I don't think I got the wrong one.

This one is listed for those years and models. Look familiar?

[Inge K.]

I believe the box said it was made in Spain.

Could be that they have put all the different temp sensors into the boxes, after the red wine siesta on Friday.

[alabrew]

No Laitch, doesn't look familiar.
Where did you find that? I looked under - You are here: Home > K Bike > Switches & Sensors   I had looked at all the sensors under K bikes. I looked at all the temperature sensors from the Parts Catalog.I even searched EME with the BMW number 13 62 2 242 184 from MAX and it did not find it. I searched with just the last three, no go.


None the less, the one I got has a black plug. I'll have to contact EME and see what they say...

Nice, I can edit. Let me apologize, I retested once I got home and it IS testing as it should. Don't know if i just had a brain fart on the meter or what. 2.47k ohms pin to body at room temp. Both pins together seem to be about both sides combined. The old one is off more comparing each pin to body.


I'll have to stop at the shop tomorrow for fork oil as I forgot to change it when I did all the other fluids and I'll get it all back together on Sunday.


Thanks for the help and sorry for the mistakes.

[BlitzenGruv]

I left the Brick at home while I went to Georgia. Brought home a '72 Triumph Bonneville project bike. Engine is all there, gearbox needs some love. The rest is all small details.
I just hope that my old back can handle the strap-ons handlebars.

[lysy40]

I bought engine bar for k75, is it an original product of bmw or custom?

[Inge K.]

Looks like BMW original teile, for K75RT only.....the part number should be stamped on the inside of the bars.
It would fit your 75S but the upper mounting is a bit different to fit to the RT fairing air outlet (higher).
It could be that this make a conflict with the S fairing, but I don't think so.
You would need longer engine front mounting screws when fitting these bars.

Back to redkote.  Don't see any way to drain off excess if the whole tank is coated.  And then the goop will get into the return pipe with ball bearing in it. So, think I'm gonna stop where I am at the seams. The old petcock tanks are no problem.  But these newer tanks have so many tubes, electric wires, etc. Has anyone coated a whole K tank? 

[mophead]

I took the filler neck thingy out of the gas cap so I can put some gas in the tank and not have the light come on so quick.

[Laitch]

Back to redkote.  . . .  Has anyone coated a whole K tank?

This member has. Consider sending him a personal message for details.

[Nine80seven]

Thanx for the link Laitch, looks like it!s possible.  My tank, however, has no bottom access panel for the float, and the only drain for the sealer would be the electrical access in the left front.  Think I'll stop with where it is.  See how it rides in the spring. 

[beemrdon]

I fixed my left side heated grip element with a really bad soldering job...but it works. :clap:

[Skunky]

Nothing too busy waxing my Skis. Val d’sair here I come

Took my forks apart to change a leaking seal and discovered that someone had fitted a 10mm high seal rather than the 8mm that should have been used. The snap ring was missing because the thicker seal covered the groove. Surprised it lasted as long as it did.
