Have you checked the fuel bowl for contaninants? Fuel pressure could also be weak or have a possible blockage. Spark plugs ok or replaced? Comment back with results, thanks.

Probably your carb needs adjustment.There are usually 2 jets on those carbs, one for the start and idle, the other for the power load. Use your manual to find the power jet adjustment screw, then follow directions to turn the adjustment screw in 1/4 turn increments until it doesn't stall under load. If you don't have the manual go to:
Find the manual download for your model.
Wish you the best!

I have what sounds like the same prob on my 1986 R80

This is a classic sign of vapor lock. Older BMW's are notorious for this. Purge the fuel lines & make sure that the choke is not sticking.
