It may be your ignition. Underneath the ignition cylinder there is an electric component soldered to a smallcircuit board(I dono what its called). I have seen that part get friedon a lot of stunt bikes. Check if that parts is broken or fried. Does anyone else know what im talking about?

yeah ive heard that. Apparently, the pink wire on the ignition is an anti theft device. When you tamper with the ignition, it fries the ignition and tells the ECM not to run the fuel pump or injectors. Now, I need a new ignition... At least it's not the ECM.

Try this and u'll be surpised what what happens....Since ur tip sensor is bypassed....Take the to wires that are twisted together (the wires that send voltage back to your fuel pump).......Unplug fuel pump from the normal connector and feed the +12 volts from the tipsensor bypass wires into the the + side of the fuel pump.....Fuel pump will cut on, relays will click, everything will go back to normal.......When it does that......Hook the fuel pump back up normal and go ride the bike.......PS: Dont ask how i discovered this, but i've had a similiar issue with a bike and that solved the problem....=-)

actually you dont need the entire ignition. You just need the bottom parts with the electical components.
