It shouldn't if the battery holds a charge and is fully charged. You can pull headlight fuse to test during the day, but this may be ******* in your state and can get you a ticket. It is most likely a fuel or valve leakage, adjustment problem.

It sounds like you are having an electrical issue. If your bikes system is not being supplied with at least 12.6+ volts, it’s starving to supply enough energy to maintain. Ensure that your charging system is working. Try putting some fuel injector cleaner through the system, as well.
It sounds like you may be picking up some trash, as well.

First check battery cable to see if it's loose, then check fuses, then check grounds. Oh yeah make sure battery is fully charged.

  1. Check your starter relay fuse. It's probably blown. If not that, (and you obviously have checked for power to the relay fuse when you push the start button, right?) then you should replace the starter relay. $10 to $20, 30 minute job if it's your first time.

You may download a manual from the following site. Power Commander Downloads

A free STDU Viewer which does a nice job of viewing PDF files exists. You may wish to give it a try.

Check the ignition coil. If the coil is tired it will break down, causing rough running and loss of rpm and fuel economy. It's possible that, without consistent spark maintaining sufficient rpm's, the charging system will also struggle which in turn affects other systems. Coils have an average lifespan of about 10 years before they fail to operate properly.

I am wondering what you mean by a K&N intake? If you mean a K&N filter, they don't always breathe as well as the OE filter and it is important not to lose the cold boxing of the original setup. I am wondering if the performance exhaust included a higher flow CAT and an extractor manifold.

If those two mods are the only changes you have made and assuming the K&N is breathing better and is properly coldboxed, etc. then clearly it is likely the engine with the original valve timing is unhappy without some air resistance at the intake/exhaust back pressure - such things often play an important role in the overall tune/performance of the engine.

My initial instinct is to suggest you take it to a specialist and have the engine management remapped.
