FI light comes on for 1/2 second, engine cuts out
Did a quick search and couldn't find anything.
Just every once in a while when riding my FI light will come on, the engine cuts out. It lasts for maybe 1/4 - 1/2 second then everything is fine again. Kinda upsetting hauling ass in a corner!
It's been very intermittent so I'm reluctant to take it to the dealer. It sounds like a short somewhere and I figure that'll be a bitch to figure out.
Anyone have similar experience, perchance?

Check the codes. That always beats just blindly checking for shorts or grounds. Another thing that I heard at the track this weekend is the intermittant open due to a loose connector. I know they snap together but alot of guys put a small zip tie around each one anyway. If someone is right on your back tire, you don't need a lapse in power that you'll both regret.

No PC.
Thanks, pilot. I had one of those Niko plus 3's that's supposed to tweak the ignition timing and such and I figured that would be the issue. I took it off and have experienced the same thing.
Will check connections, though. Zip ties ain't a bad idea.

I've had the same thing happen to me on three separate occasions in the 3+ years I've owned the bike. ('00 model, bone stock.)
The engine will cut out briefly - 1/2 second or so - the FI light will come on for a couple of seconds, then every thing returns to normal.
The first time it happened, it actually occurred three times on a 50-mile ride. The other times it has just been a one-time occurrance.
The head mechanic at the local Kawa shop, I guy whose work I respect, claims that, in his experience, the ECUs just "glitch" occasionally. I'm not sure if I buy that. I suspect moisture in the gas.

Bad gas won't make the FI lite come on though...

Well, it aint' right. Especially leaned over in second gear running at 8k rpm. No fun.

Indeed. No fun at all. :o
Not sure there's a fix. Could be that the ECU is susceptible to stray RF emissions or transient undervoltage conditions...if you can't repeat it, you can't fix it.

Yeah, Zaphod. I'm thinking stray tacheyon emmisons or sun spots. 
I can't just repeat it. That's what really sucks. Guess I need to buy the extended warranty and figure out how to fry the ECU to get a new one.
