95 KLX 250 Bogs down when clutch is pulled in
 

So my 1995 KLX250 has been stalling when i pull in the clutch when in gear while slowing down. It does not stall all the time but instead the rpms will dip and return to idle. I have not had this issue before and I have recently cleaned my carb, air filter and put in a new spark plug. I've tried adjusting the clutch cable but that does nothing but change that position at which the clutch engages. I did notice that when the bike is in gear and the clutch pulled in all the way that it is harder to push than when in neutral. Is there a chance that some clutch components may be damaged causing the clutch to not fully disengage? Any suggestions would be greatly appreciated.
