I bought a 2008 GSX650F a bit ago and have been buying and fixing it ever since, the bike will only start when battery is about to die and once it starts it wont idle... along with that, the F1 light wont go away (just flashes once started) :cry:

The bike is mostly complete except for the cosmetic stuff such as lights and plastic

Any thing that will help me start it easier or make it idle will help, along with making the F1 light go away.
One more thing, how do you tell if you have flooded it? :roll:

Thanks, Spencer

Meridian, ID

You can't actually flood the bike as it is fuel injected. If it isn't running, wrenching the throttle only operates the throttle bodies.

Also, it's not F1, it's FI. As in fuel injection warning light! :mrgreen:

What will help you out tremendously, sir, is having a service manual. If you gave me your email I could help you out big time as I have a digital copy.
What the service manual won't tell you, is to get yourself a spare piece of wire about 2" long, and strip a little bit off of each end. Take off the cover directly under your seat on it's right/rear brake side. if you look there's a little 6pin plug with what looks like a cap on it, and no other wires, like a dead end. Pull that cap off, and with the lock tab of the white plug facing up, take your wire, and connect the two right pins up and down. This will fool the motorcycle's ECU into "dealership" mode. and if you key it on, it will tell you the trouble codes a dealer would use to diagnose the problem! look them up with your service manual and you're not only on the right track, but it will advise on how best to get it back to 100% working order. Savvy?


You'll see a line, and C00 if all is apparently well. like -C00 or _C00. the line indicates the throttle position as the ECU expects it. - is dead on, and there's a high and low. not that big of a deal though, and it's not your problem more than likely.

PM me your email address, and I'll hook ya up.

If it is only starting just as the battery is about to die & wont idle properly it could also be the regulator/rectifier. If the regulator is stuffed (it's a recall anyway) the bike will be running off the battery only & when the voltage drops the idle goes rough & the dash will have all sorts of lights & indications coming on. The FI light will be one of them as the battery wont have enough power to run the injectors & ECU. Mine failed & the dash went haywire & would not run.

Fixed It!

F1 light was on for tipover sensor----

used paperclip trick and found the code which was for tipover sensor

--Unplugged and cleaned up, worked fine.... the great part is it starts on its first try and idles!
something so small could have cost me a fortune... good thing I checked....

PS-- in research there are several causes of a F1, just google GSX650F F1 Codes and the you get a list

-Thanks -Spencer

;)

Glad to help man. again, if you need that service manual... especially for the frontend rebuild...

I'm an expert at frontend teardown, as I've done it over and over and over and over... if you need any advice just ask ;)
