1999 BMW R 1100 RT (ABS) - Answered Questions & Fixed issues

Look in your owners manual there should be a code when you bought the car if you still have it.

Have you jumped the side stand switch?

after removing the front seat the back seat lifts up from the rear and then is removed by pulling it backwards

Insert and turn the key in the lock under the rear light cluster. Lift the passenger's seat off, lift the driver's seat off.

depends. if anything that loose is not so good.but some brake are design to have something loose.u can check your brake sometime there is a bolt holding your brake calliper ,cover /wrapped with a small rubber tube or washer.because some brakes there is a gap and allow your brake calliper to move a little when it brake for full brake performance.

remember that when you put hid. you have to buy the whole package thats why they made it like that. so only the hid bulb wont work with out the right amp. when you have both hid bulb and the amp. you will connect the amp to your battery n one of the cables to your head light positive wire. this will allow you to still use your switch from your handle to now turn on n off the hid. also you will have to buy a hid bulb made for your bike, do not buy any hid on the street even if they say that is universal n all that **** bcuz its not. buy the one for your bike model so it fits perfect and it locks by it self, like if it was a factory bulb. So you connect the bulb to your hid amp plug and one cable from the amp to the positive wire that comes from the bike to the factory bulb and the other one to your battery.

If you run low tire pressure you can get cupping on the sides of the tires. Tire pressure needs to be checked regularly and kept at the recommended pressure or above.
Another cause of tire cupping can be bad or loose steering head bearings. Loose bearings will cause the wheel to wobble when decelerating just like low tire pressure. It can sometimes be detected just by turning the handle bar from side to side. If it feels like the steering wants to lock in the driving straight position or you feel ripples or bumps while you turn the bar from side to side you need new steering head bearings and races.

hi this could be your battery starting to die, what you need to do is get the battery checked, if that is ok, try getting the alternator/generator checked as well this could also produce the transmission fault...hope this helps please vote thanks

try swoping the cpu if you can borrow one first
and look to see if the massflow air velve is working
the only real way to find out first time is hook it up to the computer at bmw's shop? very pricy!

There is a simple way to fix it as I've discovered. Start your bike, if lights are flashing ride for a mile or two applying the rear brake a few times. Stop the bike and place on centre stand. switch off motor then restart. Your flashing lights should have gone. Why the flashing happens is if you ride and use your rear brake rarely and then your bike sits for a day or two without use your rear brake assembly fully retracts, ie pads away from disc and ABS gizzmos inactive. The ABS sensor unit then reports extended non use pattern to the onboard 'brain' which activates the warning mode of flashing lights. This has worked for me several times over the last 5 years when its occured. Full ABS operations return. Tried it on a mates bike and it fixed same problem on his.

Yes, you should be concerned anytime the brakes on a bike act or look strange. Safety First. Have a dealer take a look at the brakes.

This is common on all bikes of this era. A new battery will resolve this problem for a while until it starts to drain down after 6 months to a year or so. The problem is the ABS system needs a good solid 12.5V or better to work at start up. This is the same time the starter also needs good power which puts a heavy load on the battery. They both end up competing with one another and the ABS computer creates a fault but the bike still starts. By starting it again and again helps because the battery is quickly charging each time you start. So, a new battery can help or put your bike on a trickle charge from time to time. The problem will never be fully resolved. You need to eliminate the fault before riding or your ABS system is non functional.

remove the starter motor cover to access the battery to starter motor cable (positive) and use anywhere on the frame for the negatve.

Water has got to something electrical, try spraying damp start on all exposed connectors also any electrical component the water may have got onto or into.

Possible failing crank position sensor

First of all change the oil and filter and use a heavier grade. If it still uses oil and is black, then you might need a rebuild.
