I have just been pulling down my new ZXR750 950 bigbore and found it has kit components in it. It does not need them but htey look good for the 400. Are the rocker arms and valve spring retainers the same in the 750 as the 400. they look the same at a glance but I have not got a 400 engine open at the moment to compare.
It has lightweight SP alluminium retainers and cross drilled followers ( rocker arms). Cheers for any help.

Regards TK400
