This means you're way to rich. could be a dirty air filter or a dead bird.

means your PC is leaking at least it's thru the valve. and because you're so rich, at higher throttle settings you can keep it going.
Quote: I switched it to prime and it didn't cut off anymore. Still couldn't get it above like 65 down a straight-away. I know the carb could use cleaning but after researching on here I thought the PC would be the easier thing to try and fix first.
still sounds like you're starving for air.
Quote:Serowbot, did you mean the gas cap? I'm not sure how I'm supposed to check it while riding
Yes, I didn't know either, only way is to pull over and shut her down, then check.
to sum it up, check the air filter.
I'd clean the carb, or at least seafoam as a 1st try at it.
your PC diaphragm could be hard or there's carp in there.
bikes that sit a long time develop nodules of corrosion on aluminum.
