I used to have trouble hearing the TPS. So I got some small compatible female connectors and some wire and made up some jumper leads. I pull off the TPS connector connect the two jumper leads and use a multimeter. :nono However I was told by two people this is the wrong way to test the TPS and the voltage put out by the multimeter will burn out the micro switch in the TPS. As this is yet to happen I will continue to set mine this way. :dunno
Regards Martin.

??????? One of the switches in there is a micro switch rated at at least 1A at 125V. If you have a meter that will burn out that switch be very careful because you will electrocute yourself with it.

My meters run on a 9V battery. I find it hard to believe that a switch designed to work on vehicle with a 12V electrical system can be damaged by a low current 9V battery.

I have an old engine wiring harness, and one of these days I hope to be able to work up the ambition to finally make a set of test leads for the various electrical bits on the engine.

Gryph I always follow expert advice 1/ Never use NGK leads OOOPS. 2/ Never test TPS with a multimeter OOOPS. 3/ Use only recommended OEM brake cylinders OOOPS. OOOPS here we go again see you in hell.

I'll save you a spot near the barbie.

Ok guys. Thanks.
I just thought it was funny that the BMW manual didnt say anything about the sw being operated by the choke.

Just next time your near your bike. Slowly twist the choke lever and give it a listen. Mine is actuating the switch at stage two.

trek97 · « **Reply #205 on:** March 11, 2017, 02:55:07 PM »

Or put your meter on it.

And let me know if yours does the same.

Martin · « **Reply #206 on:** March 11, 2017, 02:58:50 PM »

The choke switch is not a choke it just increases the idle speed, therefore as it does this it will activate the TPS.
Regards Martin.

OK I was just afraid my choke lever may be lifting too much (over the 3.5mm spec.) thus operating the TPS when it shouldnt.

Forgot to add some to the other days efforts.

Found a decent deal on a complete cluster from Canada to cannibalize for spares.

While inside I also swapped in the working clock.

Deoxit bath for connectors

Now everything works as intended.

And still have a working spare Gear board on the shelf.

Also, cleaned all the connectors I could find. Including the 3 for the speedo.

After reading they can be troublesome.

HA!!! Well this is a $15.00 error, Live and learn.

The PO had this 1/4 torn off. And I just kept pulling and prying...til I finished it off.

Found it slips right off the other end REALLY easy.

That's the classic look of a neglected engine though. One member was going to fill the murky indentations shown in your first photo with epoxy to aid future clean up or improve the look for anybody looking in there or something.

No one will see....EVER!!!

Can someone please explain the function of the throttle position switch? How does it affect the bike?

Bert Vogel explains it in this. Its description is after the troubleshooting flow chart, along with descriptions of other parts of the fuel system.

Thanks bud, I had read portions of that page. Just at the time wasnt looking for that info in particular.

Everybody probably already knows all this, but here goes.

Sweetest injector cleaner ever.

Valve stem w guts out, i drilled hole in cap just a bit smaller than tube so it fits tight or glue it in.

I pulled o-ring off injector and fit valve stem on the injector, screw on cap w tube.

injector in vise, tube in can.

First- I touched wires to battery to open injector valve. Second- hit the spray can button.

Yes but please make sure to have a friend using a grinder on a good steel bar nearby when you do...
