Hi there fellow bikers
Looking for some help I've currently got a 2004 R3 standard/classic.
The problem is no spark at the plugs??
I have checked voltages at the battery, coil feed & coil pulse sides of things these are my findings:
Battery 13.44v direct current ignition on 12.42v
engine cranking 9.96v

Coil feed, ignition off 0 volts
Ignition on 12.7v
Cranking 9.23v

Coil pulse, ignition off 0 volts
Ignition on 0.14 - 0.08v
Cranking 0.11v

Battery voltage after test 12.82v
Any thoughts!!!
 
you are going to need more voltage if you expect the rocket to start.
put a charger on it. or jump it with a car battery.

Take your battery to an Autozone or O'Reilley's to get load tested. It looks from your readings the voltage drop is severe. Also check your engine managaement relay. You can determine if the EMR is working if you have TuneECU and run the purge valve test. That test requires the relay to be closed for the purge valve to work, that has the same power source as the ignition coils (EMR).

Tried car battery jump no joy so now looking for another possible problem 👍

try jumping just the coils with another battery.
you can get to #2 outside terminal pulled the plastic off so as to jump the 12 volts and that 12 volts will feed the other 2 coils
if there is something wrong with the crank signal the the ecu will not trigger the ecu to ground the coils.

I'd start with the relays. They can fail when they get old. The most likely candidate is the Engine Managment Relay. If you have TuneECU that would also help with diagnostics.
