you are FI right?

Do you hear the pump turn on when you turn the key just before cranking? If no, check fuses.

If you hear it, and there is gas, I'd recommend pulling a plug, checking spark and smelling for fuel from the spark plug hole.

Needs to be determined if there is a power problem or a sensor/actuator problem.

the fact that it cranks tells us that all the safeties are allowing it to crank over, there just isnt ignition. Fuel, spark and compression are required to go boom.

if it cranks and you can hear the engine slowing when the cylinders compress the air, its not going to be compression(unless you overheated and locked it up, ran through water etc, compression isn't an issue)

pull a plug, preferably use a sparkplug checker grounded. If one isn't in your possesion, ground the spark plug threads on something that is grounded, not aluminium...

Do the easy stuff first.

Like Cali suggested, pull a coil pack and test for spark. You can ground it on the valve cover (Cali, why not aluminum? I've done that before... is that a no-no for some reason?)- I've used a phillips head screw driver in the cap (where the plug goes), hold the screw driver about 1/4" from the frame, and crank the engine. It's a lot easier to do with the tank removed , and that pretty well will guarantee that the fuel pump won't give fuel to the injectors because the pump is dis-connected.

As you're cranking, watch for the spark to jump from the screw driver to the frame. If it does, you're good on the spark.

Do you have an aftermarket programmer like a PCIII? You might actually try disconnecting that before even doing this test with the plugs since it could be a culprit.

I did the spark test and spark is good, no programmer or anything aftermarket other than exhaust

Could be a fuel issue then. Possibly in the primary injectors... have you checked to make sure your fuel line isn't kinked?

I know this sounds silly, but is the engine switch on the right side set to "run"? Have you done anything with the kickstand switch, or has the bike fallen over and broken the throttle side switch assembly? I'm guessing these are alright since you're getting spark, but doesn't hurt to check.

You can also pull the spark plug and bump the engine with your palm covering the spark plug hole to see if you're getting compression.

Sounds like you need to take a trip to Motorcycles Unlimited so Patrick can take a look at it for you...

so check yo fuel line!!!
+1 its happened to me as well
