I have a 1990 zx1100 that has had alot of work done on the motor. Sumtimes when I try to start it it doesn't do anything when I push the start button. Can jump the solenoid and it will start up. Other times it starts no problem but as im riding it it dies like I shut off the ignition switch. And it does it more if I'm getting into it. Im not sure what to check on it.
