Valve tappet clearance

[libor]

Hi,
I just bough CB 750 K0 and want to check and adjust valve tappet clearance. In the manual is writte IN 0,05 mm and EX O,08 mm. But it seem strange to me - sheet of paper is 0,1mm so such a 0,05 mm is practically no clearance (and the gauge is really thick(er) than a paper).
Is not it a mistake in the manual? Should not it be IN 0,5 and EX 0,8mm?
Any experiences on that, please?
Best regards
Libor

Not even nearly right.

.5 mm. is half a mm. and some .020" and only bigger car engines set that wide. It's huge.

Correct is .05 mm. (.002") IN and .08 MM. (.003") EX. The 550 uses the exact same numbers. Loosen to your suspected numbers and the valvetrain will rattle LOUDLY until it breaks which won't be long at all.

I printed paper of a thousand types and .002"-.003" is the typical thickness of a normal sheet like looseleaf for school use. Paper can drop to .0015" and go all the way up to .010" and thicker.
