There could be several issues going on, but to start with.
Is the filter clean, and oiled?
Is the compression reasonable, it should be hard to push the kick lever down with an ungloved hand ?
The exhaust should be carbon free, and the tail pipe decoked.
Make sure by observing, the power valve is actually turning, and not gummed up, also check the alignment marks when running.
The same for the autolube pump setting, check it's correct setting.
All of the above being in order, you could raise the needle one notch at a time. This is done by lowering the needle clip.
Generally there on the middle setting, but one notch of raising makes a staggering difference.
Check the main jet size as well, whilst your in the carb, ditto pilot jet.
Check the pilot jet setting, though it's input is far less dramatic.

-The filter is old and grungy, but has been cleaned...new ones are on order.
-Haven't used a compression tester to check the compression, but the kick lever is very firm.
-There is black/wet oily deposits in the end of the silencer.
-How exactly should I check the power valve and the autolube pump? I'm still new to CRMs and bikes in general.

All covered in FAQ, but basically take the covers of the two items, auto lube can be checked without the engine running,power valve needs the engine running.
A repack of the exhaust may be in order if the used oil is dribbling from the outlet. You lose quite a lot of power with gummed up exhaust wadding.

Sweet, I'll read up on those in the FAQ. I'm currently out of the country for work but when I return I'm planning on freshening up the top end, new air filter, new plug, and a Pro Circuit silencer. Maybe that will help things out. I appreciate your input

Ah yeah NGK run hotter the smaller the number I have a BR7 in mine for green laning.

Thanks for the link. Very helpful. I plan to try out the 8s when I'm able to ride it again and I'll move on to the 7s if they don't seem to be helping

Have u got throttle wide open ? That always works for me after every drop...

If it's cold it's just the choke and no throttle
