If the bike has a centrifugal clutch, the revs need to drop low enough for the clutch to disengage before you can put it in gear without grinding. Clean the carb out, making sure the slider or butterfly is moving freely, check the cable is free, and try again.

 

 

A bit of grit can get into a throttle slide anytime. Throttle butterfly spindles can stick on bikes used all day, everyday. An air leak can raise idle speed. If the idle is too fast, fix it before looking for clutch problems.

 

 

Right, just googled it, and it looks to be a similar set up to the Suzuki LT80 with a centrifugal clutch after the variator. So it could be the variator pulleys sticking, so driving the clutch at high speed all the time, or it could be the centrifugal clutch, either seized, or a shoe stuck out and grabbing the clutch drum, often due to a broken pull off spring on a shoe. Here is what the clutch, and back part of variator looks like

 

How low did you set the idle.. They are set lower than you actually think by ear i had to set it just a hair above stalling..

 

 

 

"so do you think the whole clutch needs a replacement? Also how hard of a job would that be? It’s still drive able so not sure if I would want to replace a whole part."

Take a look at it, inspection is the only way to find the fault, but at $72 for the whole thing, I doubt if they bother selling individual parts. It could just be something sticking, and may work fine once freed off. Belt replacement is a regular thing, and removing the clutch is probably needed for that, so no big deal.
