Default 01' f4i pulsing. Need help!

I have a 01' F4i that seems to have a very unique problem. About a month ago I started to notice some hesitation in all gears. The bike would act like the fuel would be cutting off. During this time the original CCT was in the bike and making that anoying noise at 5,000 rpm. So last week I had it changed thinking it could have been the problem creating the pulsing. I was wrong. Now it has been steadily getting worse. When the bike is romped on it really starts to hesitate and pulse and sometimes the FI light comes on for a couple of seconds then goes out. It recently stalled on me when coming to a stop at a light. It fired right back up. At low speeds it seems to have less hesitation and pulse action.

Any help would be greatly appreciated...

Sound like your fuel pressure regulator is going out...

I was thinking something like that myself. I also read on some other forums that it could be the kill switch sensor, but their problems were slightly different from mine.

Thank you. I think I'm going to try your thinking.

The symptoms you described were the exact samething i was experiencing. I changed the FPR and the bike ran good as new. Best of luck!

While tearing the bike apart I decided to check the battery and discovered that one of the terminals was loose. Put the bike back together and drove it around for about 15 minutes with no issues at all. It will kill me if that was the problem. I'll let you all know if my problems arise again.

i had the same thing happen to me a few months back, and after taking off and putting back on the cable to terminals it stopped. look like it was just a loose connection for both of us.

Ya I can't believe that's all it was. I've put on nearly 400 miles on the bike now and everything is perfect. It's the things that make you go Hmmm??? LOL
