I would take it back apart, inspect the clutch and pressure plate. If it's bad then I would replace the clutch assembly, resurface the flywheel, new pilot bearing, and throw our bearing. Make sure to use the alignment tool, torque the pressure plate bolts (19ft-lbs), torque the flywheel bolts (76ft-lbs), make sure you have enough tranny fluid (2.3qts honda mtf).
