I have a 97 ninja 900. It hasn't run in atleast a year. When I tried to get it started, it took a little effort to get it to fire up. Then it stalled, started, stalled, started. Now it won't even start other then the odd puff. Please help

Ricky,

Left coil feeds 1 and 4...right coil feeds 2 and 3...as long as you stick to this it doesn't matter which lead goes to which plug. Left coil will have one short lead and one long...short =1...long = 4. Right coil leads will be about even in length...doesn't matter which goes to 2 or 3.
It's a wasted spark system so plugs 1 and 4 fire together...2 and 3 fire together...only 1 cylinder in each pair will be compressed and ready to fire when the spark happens, the other will be empty and coming on to it's inlet stroke...

I have had the same problem on my RF 900. The problem was a loose fuse in-between the starting switch and starting relay. The fuse is up near the forks on a Yellow and green wire. First check batt voltage, then check kill switch, starter, inline fuse mentioned above then YG feed to Fuel pump. If all good check starter relay 30 amp fuse. If you have no power at Kill switch then check neutral light is on

All years will fit straight in...

Have you checked the wiring for the kill switch?

Then you will need to check the switch or stop mechanism. If no problem there, then you will need to replace the ignition module.

My first impression was that the battery hasn't got enough power to run the starter ans supply the computer with the 9 volts necessary to create ignition. When you push start it the battery is supplying enough voltage for the engine to start.

In short you need to service and charge the battery or a new battery.

Gummed up carburetor jets are common issue with machines that have sat for a long time. This issue is fairly universal and the usual fix is to drain out all your old fuel (save it for the mower or something) drain carb bowl. Add fresh fuel and Sea Foam fuel additive. your carb may be too gummed up for a tool free fix - if it does not run better after this, then you should clear your jets with compressed air. you access these by removing the bowl at the bottom of the carb. Once your fuel system is straight, if it still won't run right, then you may have stuck piston rings. just try to keep it running long enough, and they may free up. If not, then you'll have to replace them. Bikebandit.com for parts.

have you checked the oil pressure?
