1999 Honda Fourtrax shifting problems

My Fourtrax was running fine then kicking in fourth gear was a little hard then went in fine . The next time I started it it didn't want to shift up to any gears then learn once I got warmed up I can shifted into gears if I beat the hell out of the shifter pulling it up with my hand more like jerking it up aggressively and then we kick up in the gear wouldn't do it when it's colder though, Took the right side case off to look inside there to see if the shift arm that attaches the clutch was messed up at all and it seems fine is there anything I should look for on this side
