Cranks no start. Had local dealer come out to inspect. Diagnosed bad faulty fuel regulator. $900+$250 for oil change, spark plugs and air filter. Ordered new regulator and plenum assy. removed battery,replaced regulator, replaced battery. Cranks no start. Checked signal to fuel solenoid and found no 12 volt signal. Aplied 12 volts to solenoid and solenoid functions normally. Removed upper 1/8 pipe plug, energized gas flows freely from port. Installed upper plug. Removed lower 1/8 pipe plug, energized solenoid, gas flows freely from lower port. Install lower plug. Attempt to start manually while manually energizing fuel solenoid. No start. Checked spark at both ignition leads and found good spark. No sure where to go from here. I would think the engine would try to start is it has spark fuel and air. Choke is closed. No 12 volt signal to solenoid points me to bad control unit. I am not aware of any lockout that would prevent the engine from starting manually. What should compression be on this v-twin? Sounds normal when cranking.
We had a butterfly that was sticking that presented the exact same symptoms, cross shaft holes were slightly mis-aligned.
