Top 20 1992 BMW K 75 S Questions & Answers

Hi Paul,
Try checking the steering rod mounting bushes,the triple tree bearings and front wheel bearings!
Hope this helps!

I would check the brake pads first to see if they are worn badly, spent a lot time once learning that will cause ABS lights to flash!
Grounding the middle pin on the ABS diagnostic plug , turn on the ignition and mash both brakes to see if the bulb checker light goes out! Very important, left out of procedure on IBMWR, if the red bulb checker light doesn't go out you have a blown tail light or stop light bulb and the ABS won't reset!
Or you have a bad bulb checker module underneath the seat. If the red light goes out then the ABS lights should go to flashing then push the ABS reset button and hold for slow count of 10 or so. Release and try it. Hope this helps!

I will premise this by saying I have not taken a hiatus from riding for any longer than 18 months. So 30 years ~ WOW! My recollections after not riding for a while and getting ready for that first ride afterwards, are that balance and protection from injury in case of an accident were at the forefront of my thoughts. Well, the BMW K75s is a very well-balanced bike. Having owned one for ten years, I will never not own at least one K bike, likely not the 100 either. The handling of the bike is far superior to other bikes I have ridden, albeit only rice burners and Harleys. The K75sis a sporty looking machine, but also has great touring characteristics (who said you get only one or the other??). I would easily ride fully loaded from KC to Dallas (about 7.5 hours) stopping for little more than fuel and a strech. I guess I am a pretty big fan of the BMWs, and the K75S in particular.

With everything undone use a rubber or plastic mallet to slide the forks out

The gear moves out to engage and back when it starts, SO the starter may be shot or the gear needs cleaned and lubed

... as in you turn the key on and the starter starts running? I would look in two areas..First, find and check the start solenoid. I think it may be stuck in the 'closed' position. This could be due to one of two reasons: 1 - it is physically stuck, closing the contacts in this electrically operated switch - 2 - there is a short in a wire that keeps the solenoid charged all the time. When you press the start button, the solenoid (an electric magnet switch) is charged, pulling a plunger into a position where the battery is connected to the starter. When you release the start button, the electric magnet is turned off and the plunger (with the help of a spring) is suppose to open the contact turning off the starter.The other reason is mechanical. The starter gear may not be releasing from flywheel for some reason, probably a lever or weak or broken spring. I am not a BMW expert, but those are the things I would be looking for in your case. Good luck with your project and thanks for your interest in FixYa.com

search salvage yards online or european bikes mags--------archway in st louis may have one-------aftermarkets mite not work rite---germans made ur scooter--also see if u can repair it-buy a haynes or clymer manual for the bike

I am not a motorcycle expert, but I'm guessing your float needle is stuck, asuming you don't have fuel injection. Add a few ounces of Chevron Techron to your fuel tank. Then spray some starting fluid in the air intake, usually under the seat, and see if it starts then.

you will need to get the service manual for this. i need to give you illustrations that the manual has plus tune-up specs.

I would recommend a leak down test to distinguish if the low compression was due to ring wear or an issue with the valves/seats...cylinders bores dont just wear out from sitting.
It's very possible that the valve seals were worn allowing crankcase oil to seep into the combustion chambers, thus causeing it to smoke. Being a 3 cylinder water cooled engine it should not have an overheating issue to cause the rings to stick...unless it was neglected, and not regularly serviced, debris in the oil filter, low oil pressure.. sludge from worn out oil. A good clean air cleaner is important...bad filtration will cause premature engine wear. Install a K & N high flow filter... and your good for the life of the bike.
Hope this answers your question...good luck with your bike.

depending on your scanner you may not retrieve abs codes check fuses the usual problem is a failed or damaged abs sensor borrow or have a shop run /scan for codes

On a 2008 BMW 650i, the fuse for the headlights is located in the fuse box under the hood. The specific fuse you need is Fuse #61, which is a 20-amp fuse located in the third row of fuses from the top. To access the fuse box, open the hood and locate the black plastic cover on the right side of the engine bay. There should be a diagram on the underside of the cover showing the layout of the fuses. Once you've found the correct fuse, you can use a fuse puller or a pair of needle-nose pliers to remove it from the fuse box. It's always a good idea to check the owner's manual for your specific vehicle to get the most accurate and up-to-date information on the location and function of the various fuses.

BMW F850GS No electrical power despite good battery, fusses and FOB. I'm out of ideas

This says no fuse box.

It depends on how hot it got and for how long? Holes in the pistons under the spark plugs. Burnt Exhaust Valves. Stuck Valves. First thing to do is to remove and visually inspect the spark plugs and then test for compression. Interesting reviews and on mentions burnt valves. https://www.motorcyclenews.com/bike-reviews/bmw/r1150rt/2001/ ..
