Top 20 1998 BMW R 1100 RT (ABS) Questions & Answers

This could be a case of stripping and cleanMy the calipers but in this case I would also be looking at the front master cylinder or an internal collapse in the brake lines. This second option is not unheard of in these bikes if they are still on the original rubber brake lines. Change them to braided lines regardless as at this age they will be well past their best.

There are a number of comprehensive solutions for the BMW R1100 on youtube. Just search for "BMW Service".

the filter is in a recessed pocket on the bottom of the engine. Need a filter wrench to remove

replace plugs or maybe coils

20W50 4 stroke motorcycle oil

ABS - Anti-Lock Braking System And EBD -Electronic Brake-force Distribution In Plain English Posted by: Rohit Khurana March 1, 2010 in Automobile Technology AdvertisementCarBlogIndia Technology Articles , today I will talk of one of the most talked about safety feature called the ABS And EBD. Again I will try to keep the language simple and human understandable (which non-engineers can also make some sense of), pun intended. What Is ABS ? Anti-Lock braking System system or ABS is a safety system which prevents the wheels on a moving vehicle from locking up(or cease while rotating) while braking. ABS offers improved vehicle control over dry and especially slippery surfaces by reducing the braking distance but it can also increase the braking distance in case of loose surfaces like snow, gravel etc. Ever since the invention of ABS, it has been evolving and the recent systems not only prevent wheel locking but also electronically control the front-to-rear brake bias, which we know as Electronic brake force system, Traction control system, Emergency brake assist or Electronic stability control. Working Of ABS Advertisement When brakes are applied under heavy loads, the braking pressure becomes high resulting in heavy braking or in other words locking up of wheels. The ABS overcomes this by monitoring the wheel speed and releases pressure on each wheel brake lines in the form of rapid pulses switching between different brake lines. which prevent locking-up. Preventing lock-up under heavy braking helps the driver in maintaining control over the vehicle. In modern ABS an individual brake line is provided for each of the four wheel enabling different braking pressures for different road surfaces of the wheels. What Is EBD ? Electronic brake- force distribution system also called as Electronic brake-force limitation is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes, based on road conditions, speed, loading, etc. EBD system is always coupled with anti-lock brake-force system. The most important function of EBD is to maintain vehicular control with variation in braking pressure applied to each wheel in order to maximize stopping power. Generally most of the weight of all vehicles is carried by the front end so the EBD ensures less braking pressure at the rear end to avoid skidding. But in some EBD's the distribution of braking pressure at the rear end is more initially when the brakes are applied before the effects of weight transfer comes into play. Working of EBD system An EBD is a subsystem of the abs and its function is to control the effective adhesion utilization by the rear wheels. this definition has been given by SAE in its technical paper no. #920646. Advertisement The Antilock brake force system releases pressure in different brake lines at the time of heavy braking to prevent locking-up. The action comes in the form of releasing pressure from the braking circuit when it detects extreme and rapid deceleration in any of the four wheels in order to make sure that the driver maintains control over the steering during panic or emergency braking. For example if the wheels of a vehicle are on snow as well as asphalt then in case of emergency braking the ABS will monitor the speeds and eventually the EBD system will release less pressure for wheels on snow and more pressure for wheels on asphalt to prevent wheel lock-up

The choke actually just opens the throttle bodies a little (the bike is fuel injected). Try using putting on the 'choke', then pressing the start button, but dont touch the throttle. Does it start ok? Also, when started, if you use the 'choke' does it increase the engine speed? If it does not, then you need to set it up correctly.
Let us know how you get on.

I have a 1998 BMW r1100rt, my horn would not work and while messing with the system, I developed the following problem. My flashers and turn signels will not work, the turn signels on the left side will come on when I turn the key on but won't go off unless I pull the fuse. I need help, 165 miles to the shop. Thanks

BMW would probably want to sell you a new switch or harness depending on where the connector is in relation to the damage. Unless you are continually blowing a fuse or catching the wiring on fire, I suspect the damage causes an open circuit, which just shuts something off. Being a do-it-yourselfer I would cut away the plastic covering (with an eye towards possibly re-installing it later with minimal repairs), repair the bared wire(s) with soldering gun, solder and quality electricians take (flexable and stretchy), and either attempt to re-install the plastic cover or discard and tape the whole bundle. All work should be done with the negative (minus) battery terminal disconnected. Ray (garage owner)

I use a 'home made' paper funnel when I change both the gearbox and diff oil. Cereal packets work well!

Oil is a matter of preference,just as the brand of bike.Find a forum for your bike and see what all the other owners are using and recommend.The forums are a good source for info on specific models of bikes..Thanks

The fuel pump should engange when ignition is turned on, but then stop after a couple of seconds. This sounds like there is a fault in the fuel system, since the pump does not stop? Maybe a leak somewhere, or some defective valve. I would take it to a decent shop to have it checked, there might be fault codes they can read from the bikes electronic control system.

IF absolutely nothing happens when you hit the start button ( not even lights dimming ) then I would start by checking the safety switches.
If memory serves me that bike wont start while on the sidestand. The driver must be on the bike with the side stand up and the clutch lever pulled all the way in. Id start with those two switched first.

you have to check the wires going to the abs, could be a bad wire, if they are ok then either the new sensor is malfunctioning, or the abs sentral is fried

There has to be a way to remove the battery so that you can charge it properly. Try this site for a manual:

well you cant drill out the two bolts there hardend steel all you can do is hit them around with a sharp punch,, but try tipping in the switch some WD40 first and working it in,,it may free off after that

In short, BMW prices are directly proportional to the service history and condition.
Personally, I think $6200 is high. I bought a 2000 model RS with 15K miles for $3200, full service history, lots of factory extras - panniers, top box, tank bag, screen, seat, etc. It had a little road rash on one fairing panel, but that was $300 to put back to perfect.
I would expect to pay around $6K for a similar vintage LT, not an RT. IF it was mint, maybe 6K is the right price... I would look for between $4500-5500 for a tidy one - good tires/brakes, great exhaust, immaculate paint, full BMW service history, warranty.

flashing means its not working

check wheels sensors are working with meter

the 2 wire connection or sensor is too far away from pulse ring

Your bike has no fuel petcock. Use 15w50 in your engine and 90/130 in your differential. Haynes and Clymer both have manuals for the 1100 twins, one place to get either is here.
