PUCK

About two weeks ago my f4i died mid-circle. It just shut off. After a minute or two I got it running, however when I rev'd it, it would start cutting out for a fraction of a second here and there and then after 15 minutes it was running fine.....WEIRD. The next day I loned it to a friend who was doing a show nearby...after an hour of riding it, it completely died.

The starter will turn the motor, however it won't start. I found that it is getting fuel, but no spark. There is no damage to the wiring harness and the tip-over sensor is bypassed. I tested all the fuses, the ECU, ignition cylinder and ignition pulse generator (inside clutch cover) and all are working fine. Im all out of ideas...

DOES ANYONE KNOW WHY THE F&*$ MY BIKE ISN'T GETTING SPARK?

You're positive it's not getting spark?

PUCK

yep...100% positive

Most common problem seems to be fuel pumps going bad but if you aren't getting spark there goes that idea. ECU possibly. Got another one you could try?

Yea, I already pulled an ECU from a friends F4i and tried it in mine (no luck)...I even tried my ECU in his bike (worked fine). It's definately not the fuel pump -- it primes the way it should when I turn the red switch to "RUN". I also smell a $hit load of gas when I sit on the starter for more then 5 seconds.
