Fuel injector issue

Hey Guys,
I have a 1985 k100 that stopped running. It would randomly not start 1st try from time to time and my initial suspicion was the fuel injectors because when I was looking at buying it it wouldn't start for that reason and the mechanics cleaned them prior to purchase. 6 months later it died on me at a gas station and would not start at all.
I bought new fuel injector for it and she started right up so I took it to fill up the tank. when I got back on to ride home she wouldn't start again.
what I've done since then is the following:
-Replaced and tested the sparkplugs
-tested the fuel pressure
-tested the the electrical current at the connection to the fuel injectors
-got her to run momentarily by spraying starter fluid in the spark plug holes
-fuel does spray out the injectors
My best guess is that the new fuel injectors are just the wrong type and not delivering enough fuel but before I buy new ones I want to see what you all think. The pic is the info on the injectors I had bought. Thanks

If you bought it from a BMW dealer it would have had a BMW part number and the dealer should have matched it to your bike model and year.

If you bought it from somewhere else or a Bosch dealer then you should have looked for identification marks and checked they were the same. On older car injectors the nozzles were replaceable but still had engraved markings linked to the spec. and engine application. One bad fuel injector shouldn't stop a bike from starting and running. All 4 might.

Fuel injector issue

Before setting to work diagnosing fuel injector issues, it serves to comprehend what fuel injectors are. This segment depicts the essential methodology of how a fuel infusion framework functions and the part that fuel injectors play in this procedure.

Whatever their theory, in practice they rarely fail in a catastrophic way if you do have the correct BMW part for your bike year and VIN. It is against the odds that all four will all fail at the same time.

Perhaps your fuel tank vents are blocked or there's something else wrong with timing coming from the crank sensor? I.e, you see the spray pattern and the spark, but it is at the wrong time?

Had the same symptoms on my 84 K100RS over ten years ago. Intermittent non starting is a real pain in the arse. After chasing down a few red herrings I learnt from somewhere, forgotten where, that the pump in the early 100's was not really up to the job especially in hot conditions.
Replaced the pump from bosch and problem went away.
Just a thought.
