I've got a k6 1000,the f1 code comes up and when that does the bike goes off a cylinder,when I turn the bike off it goes back to normal again, any help would be great thanks

All questions need FULL 'year make model' as the first 3 words in all questions, or we guess.

The FI light is the equivalent of a CEL in your car. The ECU has detected an abnormality with one of the sensors, check the code and see what's up. Yes what he said...you will need a service manual to guide you through it.

FI light comes on - bike won't start!

I tried to start the bike and the FI light came on (red light) and it said FI in the odometer gauge. The bike would turn over but wouldn't start. It's done ...

Normal computer diagnostics on ignition verify engine operations. Causes include loose wiring and electrical components. Battery and normal maintenance is a conclusion for some.

F1 is no fault. put into dealer mode the little white connector under the rear seat, a bit of wire bridge the terminals and a fault code will come up, if you put a retarder on the bike try putting back to std

fuse, loose earth?

The F1 light is the FI fuel injection light. Your bike needs to be diagnosed and scanned by your dealer or trusted mechanic. There is a problem with your fuel system and a code has been registered, your bike won't start or run correctly until your mechanic has scanned, fixed and cleared the code.

well... the misfire codes are logged in when its running bad, but first I would want to verify fuel pressure when its running bad.

F1 code indicates a leak,you will find the water under bottom drawer.Lid probably not sealing well.

Hi arl3933,

The "F1" error code description is a System Watchdog Circuit. Please press "CANCEL", if beeping continues after 30 seconds, please check the main control board(ERC). Here are basic test that will help you to determine if the ERC or touchpad is defective.

1. Unplug the range power cord or turn the power off to the range at the circuit breaker.

2. Gain access inside the control panel.

3. Disconnect the touch pad (also called keypad or membrane switch) ribbon from the ERC.

4. Make sure there are no lose wires, or anything else that may cause a short when power is turned back on. Assemble the control panel back the way it was.

5. Turn the power back on.

6. Wait for at least one hour to see if the code comes back.

7. If F1 comes back, replace the ERC. If it does not, replace the touch pad.

Hope it helps.

Thank you for using FixYa.

I was at the local race shop in Milton Fl getting new rear tire and the owner of the shop took it for a spin to scuff the tire. When he got back he said he got the F1 code. He plugged a short wire looking thing into a plug under the seat. Took it to code machine and got c-11 code. which is cam position sensor I think he said. but he said he had never seen that error code before. I think the F1 blinking light indicates an error only. You have to have it analyzed with the bike running and code blinking to diagnose the exact issue. Ive got the same bike pictured above and I have been getting error codes pretty much since I bought it brand new in 08. It doesnt seem to affect anything tho, the bike runs normally. Mine usually comes on everytime I start it when its cold. but I can let it run a few seconds then restart it and most of the time the light will not come back on for the rest of my ride. Every now and then it will come on while riding. So I dont know if I'm getting more codes than the C-11 that came up for dude at bike shop or not. I should have taken mine in to have it looked at but never did cuz the bike runs normal as far as i can tell. Annoying as hell though when it comes on at night.
