Default torque specs on valve locknut

im adjusting my valves right now and was wondering if it is necessary to tighten the valve locknut to spec. I have a H23A so I believe the spec for the locknut is 20ft/lb torque. Can I just "hand tighen" or that will propose some danger. Thanks for the info

I tighten mine pretty good (i.e. tight)... forget tightening those with a torque wrench. You won't damage anything...just remember to recheck the clearance after they are finished being tightened.

Check the helm manual. The H22's torque to 14ft-lbs. Don't know about H23 off the top of my head. Using a torque wrench is a good bet unless you've done a whole bunch of them and can get close by hand. If they strip or get loose you will probably not be happy.

What the size of the locknut on the H23 engine? Is it 12mm or 10mm? I'm about to get the tool to adjust mine.

What's even worse is when you overtighten them and bend the valve stems. I've seen a couple guys do it.
