2nd gear is hard to get in at higher RPM
 

The 2nd gear is hard to get in at higher RPM on my 1996 kawasaki 300 bayou. I had this problem before. I have just bought and installed brand new clutches and spring and the problem still happens. It seems to be only 2nd gear having a problem getting into gear only under higher rpm. I have even tried adjusting the Clutch play and it still has the issue. Any idea?
