G'day ive got given a very clean ecam4004 smog head.
i was under the impression that they were poopoo but.....
It looks to me as if it has larger valves in it but im not sure??



my questions, what size valves would be run from standard for this head??
cheers

1.090" inlet, 1.000" exhaust were stock.

[edit] various websites will tell you the inlet valves on common smallbore heads are 1.062", they are WRONG!.
Go measure one, or read a factory manual if you don't believe me.
Even the old 850 had 1.090" inlets.
