this is a 1987 fzr 1000.It won’t start.the starter works and engine spins but it won’t fire up.there is plenty of gas.
I would start by spraying a little bit of starting fluid in the air intake. Try starting the bike after spraying the starter fluid. -If the bike starts up and then dies, then you have to check the fuel filter, clean the carburetors, and check for clogged fuel lines -If the bike cranks over without signs of starting at all then you might have an electrical problem with your ignition system. I would check the coils on the spark plugs and the spark plugs themselves. Good luck
