NEED A MOTORCYCLE MECHANIC HELP KAWASAKI KX80 DIRT BIKE please help me?

i have a 1997 kawasaki kx80 dirt bike. i bought the bike off someone and they blew it up. i rebuilt the top end and put a new pusher clutch in. theres something wrong with the clutch. when i start it up and shift in to gear it feels like its in neutral. then when i pull the clutch lever the clutch engages and the bike goes but the bike keeps reving high and goes real slow. i adjusted the cable and it pulls good and the clutch arm is in good working order. when i pull the clutch it pulls the acuater arm like it should so its not the cable. i also took the clutch apart and put it back together the way it should (repair book) i have no clue whats wrong some one please help me

Where the cable attaches to the motor(that little arm). Did you move it at all? My brother in law was messing with his sons 85 and took it off and when he put it back on he the cable was still hooked to it and he put it on to where it wouldn't let out far enough to engage. It would go into gear and stuff but when you release the clutch it would just sit there. It took me and him a an hour or 2 to figure it out.

when you replaced the clutch disc----did you replace the springs?--some times weak springs could cause what you discribe-----not sure what you mean by---feels like it's in nuetral----does the pressure feel weak on the lever?--have you checked cable adjustments?---pulling in a clutch lever and the bike moves forward indicates in proper adjustment ---bad springs---cable problems----pulling in the lever will disengage the clutch disc---if this is not happening---then there is a problem with the mechanism that operates this function ---either springs or adjustment ----if you are not getting full disengagement---it has to be springs or cable---those are the only two items that actuate what you are looking for---so one has to be defective or out of adjustment---
if you can compress the clutch springs with your thumb or finger-----they are bad--usually engine heat destroys the spring temper. ----
