What seems to be the problem? No accelleration. or bogging? Won't idle? Fouls sparkplugs?

I had an 83 gpz1100 with the same issue. I took all 4 injectors out and sent the to Injector R/X. I think they are in Florida. they tested them before and after. before, I had about 60% blockage. they ultrasonically cleaned them and sent them back within about 2 weeks total. WOW!!! what a difference. it was only about $20 or so per injector. worth a try for that price.

If you want some good info on the system, and how it works, Google "Bosch L-Jetronic" it will come up several technical Bosch written papers.
