What clutch does everyone suggested to use? I Burnt mine up... Also i heard the EBC gives a very stiff clutch and the stock one is EXPENSIVE! Help me out thanks!

 

if i.m thinking right barnett makes a nice clutch for the Z for around $130
EBC makes a good clutch for less money, also buy the HD springs for it

 

After doing some research I went with a barnett carbon fiber clutch. I bought it from moto-man, for ~$110.

From what I read another good setup is stock or aftermarket honda trx450r fibers with your stock Z400 plates. Then use springs from a CR500 or KX500.
