So I took the zilla down to the Oregon dunes on Saturday after I installed the AAEN pipe and silencer.  This is the first real time getting it out and stretching its' legs!I put a new clutch in it when it was being built.  It seems to slip as the RPMS get higher and your shifting through the gears. I tried adjusting the cable and what not, but it still seems to slip some.  Is this indicative of a bad clutch? Do I need to install another? Very weird, never had this happen before.  Thanks in advance.

The stock clutch springs will not usually hold the torque that the new generation large diameter pipes make.  The new generation pipes consist of the following, Aaen, Q1, Q2, DCS or HPR
