I've installed two of the BMW Coolant Temperature Kits and found it very easy. You need to install the sensor. I'm across the bay from you and if you have any problems I'll be happy to give you a few "must do" tips. The peace of mind the temp gage gives you is well worth it! You can see when your fan should kick in and won't wind up with a bad fan relay and thermostat at the same time without knowing you had a problem like what happened to me on my 1st K100RS when in summer stop-and-go traffic a few years ago.

I had to pull a cargo trailer from Maine to Seattle so I figured it would be a good idea to keep an eye on the oil temp. I added the gauge and then realized I had no idea what was hot and what was not. So, I picked an arbitrary temperature as being "too hot" and off I went. I only had to stop twice, both times in Montana, because the temperature exceeded my arbitrary maximum. Made it to Seattle safely. Later, after having shed the trailer, and in just general driving around, I discovered that there were lots of times that the oil temperature went way higher than the level that I had picked, with no cargo, no passengers, and no trailer in tow. It seems as how the normal operating temperature of the engine was way higher than I had assumed. So much for my bright idea. Dick Taylor - Classy Guy hetchinsNoSpam@NoSpammontana.com Live and lean.

For those models that have a dip stick to measure oil level, the appropriate marks are stamped on the end that sticks down into the oil.

Over the years, a number of things have been tried. The most successful I am aware of was the addition of a clear piece of fuel line added to the front of the tank on the right side. It was almost not seen, unless you were looking for it. Very clean. The ones I saw had an elbow brazed to the top and bottom of the tank and the clear hose between the two elbows. Fuel level was read from an upright position on the seat and although it was, like todays RS rider information display, only a reference to remaining fuel, it did work. The modification does require repainting the tank. -- I don't suffer from insanity.....I enjoy every minute of it!

It is located about 2" behind the rear shock lower mount, and about 2" below the rear end vent cap. Remove the Allen-headed retaining bolt, and carefully remove the sending unit, by pulling it straight out. Clean the contacts with a clean cloth, and put it all back together. This may cure your problem. It worked for me earlier this year, when I experienced the same symtoms. Cheers, Dave T.

He describes it as a bug, I would call it a quirk. There is a simple work around. you are only affected if you cross time zones, or at the change over from Standard Time to Daylight Savings Time. So, with the intro here is what he sent me: ==================================================== Hey, I discovered a bug in version 2.1 of F+. The clock can get set 12 hours off (am to pm, pm to am) when setting the hours only function. If it is 11:XX and the hour is advanced to 12:XX the am/pm does not get switched. Therefore any change 11 to 12 or 12 to 11 will cause this problem. You will see the daily info reset in the afternoon. If this happens you need to set the clock in the hours and minutes mode. If the clock is running in the 24 hour mode this problem does not happen. This has been fixed in version 3.0. ==================================================== And now back to your regular programming.... +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | "Do not give in to evil, but proceed ever more boldly against it." | | Virgil | | | | Brian Curry, 1990 Blue K75RTs both coasts, Chester Springs, PA | | The 9.25 cents a minute guy, USA SoD #23 | | | | KGN- Improving Lives Around The World | +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ From ibmwrNoSpam@NoSpamworld.std.com Mon Jul 21 01:44:53 1997 Date: Mon, 21 Jul 1997 00:20:12 -0500 From: "Chuck (Jack) Hawley" Organization: University of Illinois at Urbana-Champaign To: "Thomas E.

You have to take the little wheels apart and reglue a small plastic post inside. They are really tiny but it can be done. I used superglue. The wheels are held together with a crimp of plastic down over a metal washer. To reassemble the wheel, I glued the washer back making this a one time fix. I suppose that you can get the wheels from some speedo repair shop...or from a speedo warrenty return at a friendly BMW shop.

Take a piece of masking tape and wrap it around the top end of the bare cable (make a pointer with the tape) Push the bike thru the distance. Count the revs, do it several times. To be accurate, mark your starting point with tape, chalk, etc., on the driveway, back the bike up 10-15 ft. behind that mark and push it to the mark. At the point the front tire crosses the mark mark that point on the tire w/chalk. Get a helper if you need to. Push the bike in a STRAIGHT line to the end mark of the 52.8 ft. Count the # of revs and average them. Include this info with your speedo to Palo Alto. Be sure your front tire is aired up to whatever pressure you use, because tire circumfrunce will make a difference in accuracy. good luck!Steve Allen sgallenNoSpam@NoSpamsofnet.com ---------- > From: Paul Meredith > To: 'Steve Allen' > Cc: 'bmwmcNoSpam@NoSpamworld.std.com' > Subject: Speedo calibration > Date: Sunday, July 27, 1997 2:55 PM > > > >My gs11 speedo is pretty close to dead on (after having it sent in for calibration. > > I'm suffering with a poor R1100RT speedo.

The odo is a stepper motor and it needs pulses. Watch it closely and you will see it move in increments, not "smoothly". There are further electronics in the head that drive what I think is basically a voltmeter to indicate the speeds. One potentil fly in the ointment, is that access to the speedo potentiometer is the pits. I think it is remove the speedo/odo, adjust, reconnect and retest. But this is not a reason not to make the test box, which IMO, is very trick. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | "Do not give in to evil, but proceed ever more boldly against it." | | Virgil | | | | Brian Curry, 1990 Blue K75RTs both coasts, Chester Springs, PA | | The 9.25 cents a minute guy, USA SoD #23 | | | | KGN- Improving Lives Around The World | +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ From Bill Heckel Date: Mon, 18 Aug 1997 11:31:05 -0400 From: Bill Heckel Subject: BMW: How to, clock mod on 1175 chip clock.

I did the contacts thing, and I even resoldered many of the solder "lines" on the circuit board, as well as the solder "blobs" holding the capcitors, etc, onto the board. The problem came back, associated with a loose washer within the speedo. It was a retaining washer associated with the odometer reset knob. Apparently it moved around inside the speedo, and whenever it rested against a couple of contacts the speedometer died. Look for a stray metal part inside the unit. Good luck.

If I'm not mistaken, as per what Jon says above, those marks indicate the maximum recommended speed for the gear (2 "lugs" = 2nd gear, 3 lugs = third, etc.).

Your ground speed will vary with tire size for a given engine RPM, but the tach and speedo will still read in synch together unless you have the clutch pulled. The speedometer pickup is mounted on the final drive and detects pulses from the toothed ring in the final drive. The tack opertes off of engine ignition pulses. Since the engine and final drive are mechanically connected to each other via transmission and shaft - for any given gear they are directly locked together at a certain ratio. For the curious, the same situation is true of airhead boxers - the speedo pickup is a geared worm drive at the transmission output shaft and is mechanially linked to the engine. Now, for R11's, this is not true - the speedo drive is off the front wheel. >From: "Adam Wolkoff" >Subject: Re: BMW: K1100 Speedo Calibration > >> What kind of tires are you running?

Well I may have a fix to try before you spend several hundred dollars replacing the speedometer. I have a 1985 K100RS which this would happen for no apparent reason. After having the circuit board replaced it still occurred. At the dealer I was told that the speedometer would need to be replaced at a cost over $250. I decided to wait since I already spent several hundred dollars on it. What I did to fix this was to follow the wires from the pickup unit on the final drive along the swingarm up behind the right side cover. There you will find a connector. Pull this connector apart. Spray some contact cleaner on the contacts and scrap the contacts inside and out with a small screwdriver and reconnect. I did this about 3 years ago and haven't had any more problems since. I still have the original speedometer and it has about 135,000 miles on it.
