Question about 1977 BMW R 75-7

1 Answer

Coupling is stuck / sticks together

After the winter, I tried to get my motor BMW 75/7 back on the road. Starting is no problem. But when I hold in the clutch (coupling - I don't know the right word) and I want to put him in first gear, he shoots forward and falls out. The clutch/coupling seems not to work anymore. It is probably stuck or it sticks together somewhere. I allready tied to hold in the clutch for one day without succes and I tried to start it in first gear also without succes. Do you have any usefull tips ?

Is the bike shooting forward while you have the clutch lever pulled in or when you let it out? If it's when you let it out you have to do it slower and roll on the accelerator so that it doesn't stall. If you have the clutch lever all of the way in and it shoots forward you may need to see a mechanic... I'm sorry if this doesn't help much.

What you have here is a clutch plate that is stuck against the flywheel. You can try a couple of things. First the safe thing is to put it on the center stand and put it in 4th gear. Hold the clutch in and Grab the rear wheel and rock it back and forth severel times quite hard and this may free the plate That is the simpleest and safest way to do it. donnyb60

The problem may be the clutch thrust bearing,if it seizes and you pull in the handlebar lever the mechanism may get damaged . A lot of play in the lever and rough action with no effect on the clutch is the result.It may just be the clutch plate slightly seized the results of this are proper handlebr lever action but as soon as you put the bike in gear in jumps forward ,try running the engine at tickover for 30 minutes to really warm up the bike then put it in gear,after a few trys things should free up.

1 Answer

1998 BMW R 1100 RT starter won't turn over. Bike won't start.


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

Anti lock brake lights flashing simultaneously


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!

Start and die


Fill up the gas tank, clean the fuel filter, and then check to see if your carb jets are clean. Remove the jets from the carb and attempt to look through them in the light. If you cannot see light through them they need another cleaning.
