Recently fuel tank contamination apparently did a number on the fuel pump and filter on my 1994 K75. After cleaning the tank, I found, as expected, the fuel injectors were apparently blocked and not working.
I elected to try to clean them myself.
I wish I could tell you I came up with this, but I did not. Here is a link to the video where I got the idea. He is working on injectors from a modern BMW R-bike. His cleaner appears at about 7:30 into the video.
And to the right is my interpretation of the same cleaner.
The switch is a micro switch from the junk box. I did not have the proper connector so I had to adapt some female connectors from a plug - also from the junk box. The syringe I found for $1 in the veterinary department of our local feed store (click on the images to make them larger). I did replace all the O-rings (FEL-PRO ES 70599 - at the local auto parts store) - about $8 for two packages of 4.
The cleaner proved very successful.
I used ethanol (denatured alcohol) first, then B-12 Chemtool. I think the ethanol did the most good for the contamination I had.
Re-fitted the injectors to the rail (which I also cleaned), buttoned everything up and the K75 started up after about 3 seconds of cranking.
Very pleased. My sincere thanks to Doug Rost.
