Bike does not accelerate like it should? even the sound is different. recently changed clutch plates. ?

my clutch plates were damaged after like 1300 kms in operation. now i changed the plates the bike does not accelerate like it should. what might be the problem. my bike sounds different too. in neutral, it sounds different when the clutch is pressed and different when it released. what might be the problem???|||if you didnt keep track of the stack sequence you could have them stacked wrong and if its a wet clutch did you soak them before installation? if not you will get some pretty wild performance . does the engine wind up and the bike not respond if so the clutch is slipping check all adjustments , its not hard to over tighten the cable, also causing major problems|||id start by checking the order you put the plates and friction pads in
