I had a spark plug that was black with soot and was suspecting a sticking fuel injector. (1985 K100RS)
In researching injectors I came across the 4-hole Bosch injector part#0280150941 which is suppose to work well. Unfortunately after changing all 4 injectors the bike runs very badly. I pulled the fuel rail and the injectors are all shooting fuel. Put the old injectors back in and bike runs fine.
The injectors I purchased where rebuilt off E bay. Are they bad or just the wrong part?

Wrong ones. The ones you want fit the BMW 318i
-
Why not just send the originals out to be cleaned and serviced....
I can't answer if the e-bay ones you got have the same fuel flow volume rating or not.
-
Whats the ohm rate and flow ratings of the originals and the ebay ones?

I had read that the 4-hole injectors made the bike run better. More torque, better fuel economy.

The 0280150941 should be pretty close, but the resistance is lower than the stock 0280150210.
The green ones from a 318 are a 0280150211. I think that is what most folks are running, that is what I am running.
I tried some 0280155962's but they didn't seem to work right. I think that my fuel pump may have been failing so I don't know if they were okay or not. The 962's don't have the slot for the clips used on our bikes, but it shouldn't make than much difference, they didn't leak. The 962's are the newer style one piece that supposedly don't develop leaks like the larger (our stockers) do.
Witch hunter has great pics and flow rates for fuel injectors http://www.witchhunter.com/injectordata1.php (http://www.witchhunter.com/injectordata1.php)

The 4 hole injectors I got from eBay worked great but then again I also rebuilt the entire fuel system,around 500 dollars in parts. Injectors, all fuel lines inside and outside the tank fuel pump and rubber mount, and last but not least the fuel filter. . You can get a full stock fuel replacement kit on line for about 300...
