"With the Ferrea Subaru valves you will not have to have the ends re-hardened as the tip is quite long and will still be present after shortening.
"gas flowed", a fancy name for back cut, I tried that as I explained earlier the flow might be better at low lift, but you may loose out on air fuel homogenization so perhaps a compromise.
As far as cost goes I would be outright embarrassed to sell valves at a price that others seem to be quite happy to do."
fact
the first point is rubbish. the hardening is visible and stops well before the cutting point.
fact
actually, the flow is poorer at 1mm, equal at 2mm and 30% better then reducing to 10% at max lift. (this is from memory)
if your running larger than a 165MJ you'll always have trouble atomising neat fuel.
If i'm embarrased at 90gbp - what are KTM valves at 105-110gbp?
I'm not embarassed at all!
ANYONE WHO WANTS THEM CHEAPER CAN HAVE THEM CHEAPER - by just asking me "how" (except you of course)
