All of a sudden my FI light came on any idea what would cause this manual says take to dealer but i figured Id check here first. Bike has 1600+ miles, the spark plugs been changed the oils been changed. one more thing but I dont think this should have caused this today I jumpered the clutch lever safety switch cause the original contact switch broke but I really don.'t think thats the why but i could be wrong???

1600 miles and the plugs have been changed and the safety switch is already broken? WTH ???
You probably forgot to hook something back up when you changed the plugs.

You can pull the code with the dealer mode plug,find out what it's doing. Thats a start. As far as the clutch switch goes, if I were you I would definitely get a pressure switch to replace the one that broke.
yep don't jumper clutch switch, you are causing all kinds of problems and don't even know it

X2!!! Yup...that's the Problem! Fix your Clutch Switch and FI will Most Likely(almost Guarantee it)go away.
well not sure about FI going away, but you turn a very high tech ecu into an abacus by jumpering clutch switch. you run in all the wrong maps, early limiter, 2d timing table etc.

Did on My Busa when I jumped the Clutch Switch.....Not at Idle though, Lit it after riding for a Bit.
maybe a gen 2 thing, never heard of a gen1 doing that, though surely possible LOL
Also check injector plugs. If you were moving around in there you might have hit one. I chased an F1 light for a couple weeks and found out a contact in one of the injector plugs was loose.

Pull the code... narrows it down quickly.

I figured out my code easily when I had an FI light. Turned out to be a bent pin in my Bazzaz harness and easily fixed.

I see there is one or two pics that I moved so they are not showing in the thread. Let me know if you need those and I will repost on my thread from 2012.
I'll check back here over the next few days or you can PM me.
