I recently (4 months ago) bought a 87 k75 that sat for 10 years with fuel in the tank. i replaired the holes in the tank, bought a new $fuel pump, filter, hoses and pump mounting rubber. I put in a fully charged battery and the motor turns over but will not start. I have no cvlue how fuel injection works. What is the order of attack to get this bike running? What do i look for?
