TRYING TO START THIS THING FOR A FEW DAYS NOW, WHAT I HAVE CHECKED TO BE IN GOOD WORKING ORDER: CARBURETORS ,STARTER, SOLENOID,FUSES,RELAYS, SWITCHES, AND BRAND NEW BATTERY.NOTHING HAPPENS WHEN TRY TO START THE BIKE, DON'T HEAR THE FUEL PUMP CLICKING, DID TRY A HARD STARTING "BYPASSING THE SWITCH AND STRAIGHT TO STARTER SOLENOID TO STARTER" MOTOR IS CRANKING BUT WON'T TURN OVER... Noob TRY STARTER FLUID AND STILL IT WON'T TURN OVER..ANY SUGGESTIONS IS GREATLY APPRECIATED.

are the plugs wet to prove its getting fuel as you mention the pump not clicking? it usually stops clicking once the system is up to pressure

Side stand switch faulty? Do you have a spark when it cranks? How can it crank if its not turning over (both same meaning) is it cranking but not firing?

The fuel pump should prime when the ignition is initially switched on if the float bowls are empty.
IIRC the fuel pump relay also controls the safety cut out circuits; sidestand and clutch in switch over ride.
The starter will not operate if the sidestand switch is gummed up/ faulty.
This relay also controls the TCI unit and will prevent ignition.

This may be why there was no ignition when you attempted to bridge the solenoid.

Worth a look anyhow; you seem to have all other bases covered.

This is a 1000 R ?

(Stig posted whilst I was still composing;there is some duplication. )

Test the pump:
  • Disconnect the pump connector
    Wire bLue/Black to +12v; wire Black to GND
    Does the pump come on?
Test the fuel pump relay:
  • Disconnect the 6-pin connector at the TCI
    Jump the bLue / Red wire (lower center) to the Black wire (lower left, facing wires, pins away)
    Does the pump come on? Does the relay click?
Do you have spark? It won't spark! Now what?

If the pump comes on or the relay clicks when jumpered, and you have no spark, then your TCI is baked.
