1982 Kawasaki GPZ1100 fuel injected throttle response problems
16 Jun 2026 10:10
When I start the bike, the idle is not spot on and fumbles badly from 3000 on. If I blip the throttle it will sometimes just die.
Here is what I have done so far: New plugs, injector cleaner put in gas, pulled the connecter from the DFI/TPS and cleaned with right product. Measure the ohms resistance on the plug and between the left to far right is 6.9 ohms, between the left to next over no reading. I was told that with this bike that the middle connector is on a separate sensor and I could test it by using the buzz option of my meter but still no response or sound. When I test the ohm reading and open the throttle again there is no change. Can't tell if it is starving for gas or getting too much. Checked temperature of the pipes after running and they were all pretty even, so I have concluded that the cylinders are all definitely firing. It seems that I need to get deeper into checking sensors but not sure which ones? Will put up a picture on next post. Thank you for the privilege of being able to ask people who have already experienced the problems. John

Hi and welcome from the UK. Here is a couple of previous threads that might help although don't forget you still have intake rubbers that harden and leak and also rubber injector seals which will also harden and leak
PS: fuel additive won't clear clogged up injectors no matter what it says on the tin !!!!
