Have you checked the lithium crystals Scotty?
I know, bad joke. I'ld check the compression first. That will tell how the top end is and doesn't require any tear down. If that's good take a look into the carb. There is a thread in the technical section about the poor mans carb cleaning. You can remove the throttle cables and tilt the carb out the right side and get to the float bowl from the left side. See how much gunk you have in the float bowl. You can remove the jets and gently run a thin piece of piano wire through them. A few people recommend running Sea Foam to clean things out or at the very least, I believe as a preventative measure.
Good luck and let us know how you make out.
