I saw an earlier post on the old site regarding the same issue I am having but no answers as to what the fix was. I have an 03' R6 and was riding home yesterday morning when all of the sudden the bike just acted like it was running out of gas. I tried to pull over from the Hyper lane on the freeway in los angeles and as I twisted the throttle the rpm's just stayed at idle I finally got it to the side of the road and tried again to twist the throttle open and again NOTHING but idle. So I shut the bike off and re-started in a couple of minutes and it fired up and seemed to ride fine for about 10 minutes then did it again. As I said in the titole I really can't afford to pay the 300 that the Local dealers want just to trouble shoot the issue and since there was an earlier post I figured I would just ask what the fix was.

any help in this matter is truly appreciated

Thanks
Ron

Does it sound like it's misfiring or if it's running on 3 cylinders?
It's possible you have a bad ignition coil (s) which is causing it to run on 3 or possibly 2 cylinders. Usually depending on which cylinder coil it is your bike will have a dead spot in that certain RPM range.
If you are twisting the throttle and are getting no response then somethin is really messed up. Check your throttle cables to make sure they are hooked up and working properly and that they are not broken.

It Actually feels like its running on one cylinder and then it just starts idling and the rpms won't move when I twist the throttle. I already had the coil recall done and as you can see at the bottom of my post those are all the mods I have done. I can't figure it out and its really frustrating thanks.

Thanks again for your help

the other cylinders would race when he twisted the throttle like he did, if that was the case. i was thinking its the voltage regulator, it was a common problem for the 03 - 04's i think there was even a recall. dont know what the test would be to rule that out, but maybe something else for your search.

Are you talking about the rectifier? If that was the problem it would kill the battery and lose power and it wouldn't act like it was running on one cyclinder.
It has already happened to me and I thought I had a dead battery and I kept hooking it up to the battery charger and would go ride and bout half hour later it went dead again. It didn't affect throttle or power response whatsoever.

What I can't figure out is why it won't do anything when you twist the throttle?
Maybe the cable came off on the throttle bodies or you need to adjust freeplay or possibly a broken cable. Other than that I don't know.

yeah thats it, rectumfire. i was sleepy last night and couldnt remember that.

Check the TPS? If the TPS is messed up then the ECU might not adjust enough for the gas. I think it uses the position to do some funky calculations to determine the max output and when to fire the piston and stuff. What you can do is ride around your block until its happens turn off the bike hold the two buttons on your display turn on the key and wait until it says diag. Then release and press them again for another 2 to 5 seconds. The first diag1: should read 0-20 and when you twist the throttle its should go up to 90-100 ish... oh yeah make sure the kill switch is on.

You could have some bad gas...water or trash in the tank. Its not too hard to pull your tank off the bike, flip it upside down and pull out the fuel petcock. Attached to that is a screen. If its dirty or cloged thats the problem. If its really clean you could still have a little water in the tank, it doesnt take much to kill the engine or make it run like crap. If thats not the problem I would start looking at the Throttle Position Sensor (TPS).

Just judging by your description Idont think its a fire to the plug problem or in my opinion it would shut off completely. If it will idle its getting fire but might not be getting enough gas or enough air.

I truly appreciate the help and info given by all I will start with the tank and fuel pump and troubleshoot the TPS and MAF after then move on. But again thanks to all.

Please keep us update on what you find. I notice a lot of people who ask or help either resolved it and then left and not tell us anything. This would help anyone that have this issue.

It sure sounds like the ole Coil problem.
