Check your battery for loose connections.
Or if you have a power commander, try bypassing it.

Does the fuel pump prime when you turn the key on?
If not, that could be a problem also.
Have you jumpered the green service connector and switched the bike on to view the error codes? It may give a clue (or not).

And yes I'd try disconnecting the power commander from the system to test.
Of course it may not run perfect, but it may helpful to know it was or wasn't the problem.
If you have the PCIIIUSB, the you only have to reconnect the gray connectors on the left side of the engine.
If you have a PCIIIr, then you'll also have reconnect the red OEM connectors from the pulse generator coming out of the alternator at the lower front on the engine.

Hello SubSailor ... I had an 02 a few years ago and remember just snapping the clutch in second gear and the front end came up easy. I bought another 02 ... seems WAY taller geared , can only get the front up in first. I barely get out of first in town. Not ever going to top this thing out and prefer a shorter shifting ratio. What teeth combo do you suggest with the sprockets ? I hope this question made sense !! I am going to count the teeth now. Thanks ... Mike

The stock final ratio is 16F and 40R.
The more popular final ratios are 15F and anywhere from 41 to 43R.
This allows the engine to run closer to the torque and power range.
While this may sound geared down quite a bit, the bike still has plenty of top end.
More than enough to land you in jail or a stiff fine.

You say you already have a 41T rear sprocket, so the unknown is the front.
You can probably guess it's either a 16T or 15T.

Hey UPSGUY,
PM'd you. What did you end up finding wrong with your bike? Currious because mine is acting up.
