How do you take off back seat on bmw r1100 rt 1999

SOURCE: Hello, My 1999 BMW RT 1100

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.

Alex ,
the battery is not your problem . it sound more like the starter motor giving you grief or alternator or regulator .
The electronic system on these are Bosch which are very sensitive to fluctuations of power .
Now when your starter draw power it really sucks power out of your battery and hopefully you have enough for the rest of the appliances .
the hard line of all this is that the battery may look good and hold the charge for a while but once the starter motor draw power to start the bike , you have very little power left to service the rest of power needed for the electronics . Make sure the alternator give you enough charge , test it while running , it should give you between 13.5 V to 14.8 V output or see if you accelerate the bike the headlight becomes brighter . If the light stays dole or dimms while giving a bit of gas , your alternator or regulator has a problem and will have to be tested and replaced .
have a look at all this and let me know how you go

Because the fluid services both side evenly, you should only need to bleed the LHS. Just bleed it the same as you would a normal hydraulic system.

Put a small piece of plastic tubing over the bleeder valve, and make it as airtight as possible, I generally lock it with a piece of brass wire.
Place this into a jar with enough brake fluid to cover the bottom of the tube. Open the reservoir, it is easier with two people, open the bleeder valve, and pump like carzy, adding more fluid to the reservoir as required until no bubbles appear in the jar. Then lock off the bleeder valve and clean up the mess, after re-fitting the reservoir cover.

SOURCE: ABS light will not reset

What ABS sensor did you replace? Front or Rear and did you shim it?
Try riding the bike down the road, turn ignition off (NOT to the steering lock) , turn ignition back on and restart bike in any gear while the bike is moving, this resets the ABS control unit.If the ABS light comes back on the bike has a current problem (sensor,wiring or control unit)

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.
