Hi,

I messure 11.4 volts at my coils with the ignition on, and motor off. Battery messures 12.7v

Im having troubles with my right cylinder not firing up, and the spark seems very weak when I put the plug against the engine block.

i tried cleaning the ignition switch, handlebar killswitch and going through the connections.

is it normal to have a voltage drop like that at the coils? (Red/white wire)
