I just recently replaced my clutch in my 1999 Honda 400ex. I changed the oil and put in 10w-40 that is safe for a wet clutch. The clutch will stop disengaging once the engine is hot. I can also hear a clank like metal hitting something when I shift into 1st or 2nd gear sometimes. I don't know what the problem is exactly. If anybody knows what's wrong please help. ThanksI:I
