hrc valve specs

[400cc]

does anyone know the actual valve clearances for the intake and exhaust for a 04 hrc cam?

It is the same for any cam you install.

Intake: .006 +- .001
Exhaust: .011 +- .001

nope- depends on cam manu and material type.

i found another source for valve specs and this is what it says for the valve specs

Exhaust: .28 mm +/- .03 mm
Intake: .16 mm +/- .03 mm

isn't that a little to big?

here is a shortcut for the service manual

A=(B-C)+D
A is new shim thickness
B is recorded valve clearance
C is specified valve clearance
D is old shim thickness

recomended clearance
intake is .16mm(+or-).03 or .006in(+or-).01
exhaustis.28mm(+or-).03 or .011in(+or-).01
on page 4-12 of service manual
