Firebolt error codes, TPS?

[firebolt99]

The clutch plates look fine and are the recommended thickness in the manual, I'm not exactly sure what else I'm looking for but I don't see any parts that are too worn or broken. What parts should I be taking a closer look at?

Check the clutch basket and Hub for any broken or missing parts.
Are you the original owner of the bike?
If not then check to make sure you have the right number of steel plates and friction plates inside the clutch basket.
Make sure the spring at the bottom or the clutch pack is facing the correct way. Or that it even exists. I'm familiar with an 07. So check with your service manual concerning the plates and their orientation.
Did your primary cover have any wear or cracks on it in the area where the clutch adjustment/actuation mechanism sits? I can't think of the actual name of the part but it's what the clutch cable connects to.
BTW you mentioned at the beginning of this post that you had a TPS code. Did you get that sorted out before you started taking things apart?
If your TPS isn't working properly you could have the throttle physically wide open but the ECM might be receiving a signal from the TPS that contradicts the throttle position. Hence limiting the amount of fuel/air actually going into the combustion camber. Then limiting power. It's a stretch, I know, but if nothing is wrong with the actual clutch mechanism I don't know what else to tell you.
Maybe someone with more knowledge then myself will chime in and have the right answers.
I hope I'm not confusing you or misleading you. I'm just giving suggestions based on my knowledge and experience.
Good luck

Thank you for your input. I'm the second owner, I bought it from a friend that I've rode regularly with since he got it, he had wrecked it before but had it all repaired and put 4000 miles on it after the wreck and it had no issues. I didn't see anything missing or broken in the clutch basket and hub, and the part that the clutch cable connects to looks fine as well. There are no cracks or wear in the primary cover or derby cover. Right now with the bike not running on a rear stand no matter what gear it is in the back tire will spin freely if pushed, sometimes making a type of grinding/squeaking noise as it spins. I haven't done anything with the tps yet because I wasn't sure if it had anything to do with the back tire freely spinning while in gear.

If you're absolutely positive everything inside the primary is sound then you'll have to split the cases to see what's going on inside the transmission.
If the engine started, idled and revved as it should, then there has to be something going on inside the transmission that is causing the engine power not to transfer to the rear wheel.
The rear pulley and countershaft(engine) sprocket are in good shape right? Have you pulled the engine sprocket to make sure the splines aren't stripped or something?
And you did inspect your drive belt? There aren't any teeth missing or anything that could cause it to slip?
