Hello, I am new to this site but not to the frustration of having a bike I love so much frustrating the hell out of me. I have a 2000X-1
Race ECM, Pro Series Muffler, and a new intake from American Sportbike.
Coming back from some canyon carving last weekend, I popped a wheelie that fell short due to a blown ignition fuse. It was constantly blowing them when I was popping wheelies so I stopped. Today when I was on my way back from an easy ride it started blowing fuses when I would open up the throttle all the way. Then even trying to keep up with traffic. After loading the bike in my trailer I took the whole bike apart and found nothing wrong. I reassemled the bike and took it for a ride, and after ten or so wheelies I rode home with the same fuse, still good. My buddy says it could be the voltage regulator.
What the hell is wrong with my bike?
Sorry for the novel....

The voltage regulator feeds the battery directly through the 30 amp breaker, and if the voltage goes high the ECM only posts an error code - IMHO, I don't think it could be the regulator. The regulator could be completely disconnected and then ride (briefly), the battery obviously wouldn't be charging, and the stator would have a high voltage on it.
The ignition fuse feeds the fuel pump, ignition coils, fuel injectors, the ECM, and all the sensors. The ignition fuse feeds the power to the kill switch by the throttle - when you whack the throttle is something shorting this to ground? The coil and injectors are constantly fed the positive voltage and the ECM closes the ground connection to fire them - are the throttle cables moving the wires? Or the clutch cable?
The speedo sensor is also fed from the ignition fuse, (and is known to sometimes short). Disconnect it and ride - the wires may be touching under acceleration?
The fuel pump is also constantly fed the positive 12 volts and is turned on by the ground connection through the ECM - check the wiring?
The fuse also feeds the datalink connector under the right front of the tank, wire could be rubbing on frame?
The throttle position sensor, cam position sensor, and intake air sensors get their power indirectly through the ECM, so I doubt they would blow the fuse. The bank angle sensor is fed directly from the fuse.
The ignition also has it's own ground connection (under the rear of the gas tank) - if it was intermittent the surge may blow the fuse.
It may be necessary to power some of the above items from a separate temporary fuse to track down the fault.
Good luck......

I agree with 99x1. If the voltage regulator went, you would not see a problem until your battery was discharged or burned up.

Something is shorting to ground somewhere. It'll be annoying to track down, but probably easy to fix.

one place to check for shorts would be where the cables and wires go down by the bottom edge of the triple trees. It can be as sharp as a knife there.

Thank you, I will look around and see, and let you guys know, for me I guess it will be unhappy hunting.
