Really? My manual says
(hot)
inlet 0.15mm
Outlet 0.25mm

Cheater, yours are about 0.25 and 0.3, yes? Am I gonna be burning valves?

Yep, I know, and they are equivalent to 0.25 and 0.3 mil. Quite a bit larger gap than what I've been using.

I set up my valves hot at 0.008" ( 0.20 mm ) inlet and 0.010" ( 0.25 mm ) but the spec sheet for the cam gives these figures

you are pretty safe 0.008" and 0.010"

I fitted roller rockers with hydraulic lifters. Never have to worry about clearances ever again. Only down side is that they rattle for about 10 seconds after motor has started till they pump up properly. ;)

mate the biggest downside is the crapy hyd profile that
good for about 4600rpm
hyd cams suck bad
and you cant get a aftermarket one

My rev limiter is set at 5500rpm, hydraulic lifters are OK till then, but beyond, your into solid lifter country. ;)
