Q What’s up with my GSX-R’S fuel injection system?
I’ve taken delivery of a GSX-R1000K1 which seems pretty tidy but I’ve noticed that the FI (fuel injection) warning light sometimes stays on. If I stop the engine with the kill switch and then start it again the light goes off and if the light isn’t on when I start up, it doesn’t appear while I am riding. Geoff Hawksley, Cambridge
Answered by Gareth Hall, Redcar Suzuki My money is on a sticking exhaust valve. There’s a butterfly valve in the link pipe for noise regs that gets a ‘check-sweep’ when you switch on. If the battery is a bit tired or the cables are sticky that will trigger the FI light, but then it gets another bite at the cherry when you flick the kill switch and that can be enough to clear it.
There’s a white four-pin plug under the seat that you can short to get the fault code on the dash although it will only show this while the fault is ‘active’. Many K1s will have had the valve and warning light wire disconnected by now. The one you need is the black wire with the brown tracer on the bottom row of the 34-pin connector for the ECU under the rider’s seat.
