Hey Guys, I'm new to the forum, thanks in advance for all the help!

Okay, heres a doozy:

I have an 05 daytona 650, 12k miles on it, I also have a radar detector hard wired in(fused of course) which I UNPLUG after I turn the bike off, not just turn the off switch. It has ran perfectly fine up until about two months ago, here is the rundown:

The battery was due for a service, so I bought a new one from the local dealer and installed it. No problems whatsoever. I then changed my oil with full synthetic. No problems again.

About two months ago, The bike began dying at stoplights intermittently, whenever I let the throttle off to idle. I can keep the throttle back and the bike stays alive, but as soon as I let off, it dies. It starts up fine and idles excellent cold and idles at lights fine sometimes. It is not a consistent problem. I figured it may be an air filter or spark problem, so I replaced both. I put iridium plugs in and the problem went away for about a day. I pulled the plugs and none were fouled, and all were properly gapped. I put them back in and made sure that the coils were pushed down and the plugs torqued. Still, it dies at stoplights. I pulled the plugs and put stock plugs in (new ones, not iridium) and exchanged the battery for a new one. Still dies at idle.

Note: The check engine light is on, so I took it to my dealer and the only code it was throwing was for 'secondary air injection'.

Here is the weird part: It will always have problems starting after I fill it up with gas, no matter how much or how little I put in. It will BARELY crank over, and then it will not idle, only die immediately. I have to hold the throttle back to keep it alive after gassing up. Also, if I pull the throttle to give it gas to start my speedo will always read '0' when I start riding.

Another curious question: When I turn on the ignition the tach needle jumps VERY quickly all the way up, then all the way back. It does not go up and back smoothly. Only a quick jump. Is this normal?

Thanks!

Im not an expert, but I'll throw out my opinion.

First thing that came to my mind is the AIC Valve.

#24 in the schematic below ...

If it's not that, you may want to check out the idle control system (I forget what it's called.... I can check if you want.) It's attached to the throttle bodies on the right hand side and it's basically a set of motors (maybe part of the choke system)

My bike is throwing a code for it, and it will die every once in a while (still can't ride it, but at idle) And if I hold the throttle open at all, it'll be fine.

Thanks guys, I'll check out both possibilities and report back to you. What do you guys think about it happening consistently everytime I fill up with gas? After I fill up, it *appears* that the battery doesn't have many amps left in it and can barely crank.

Also: Does your needle sweep smoothly or does it 'jump' like mine?

Thanks!
