I have a 2007 gsxr 1000 only running on 3 cylinders. Brand new plugs, did resistance check on all 4 coils and everything is in spec.
Weird thing is is when I swap coils from cylinder 2 (dead cylinder) to cylinder 3 the problem doesn't move. I have spark in the cylinder and when i pull the injectors from the throttle bodies and try to fire the injector on 2 cylinder is spraying fuel also.
Cant figure out what would be my next step from here, any help would be greatly appreciated.
Check all your vacuum lines that are on the back of the throttle bodies. One for each cylinder, I had one off one time and it felt like the bike was only running on 3. Did you check fuel and spark by grounding the spark plug while its in the cool pack? Also make sure your fuel line isn't kinking when letting the tank down.
Sometimes it feels like its running on 3 when there's a vacuum leak or fuel shortage
If you have a power commander, that might be the problem. Disconnect it to see if that's the problem. If not, then pull the side fairings and start the bike for about 30 seconds, then touch each pipe to see if they are all hot. Be careful not to hold your fingers on there and get burned. If one is cold then you know which one, and then try to change that injector. It may not be getting enough fuel.
Did you try swapping out #2 injector with one of the other good holes to confirm the injector is good ? I would assume the ecm controls ground to fire the injector. Did you check to make sure you are getting battery voltage to the injector ? I would probly check voltage next and if that's good swap the injector if it was me.
