Need Help On Specs

[Pogo]

Wondering what the valve (tappet) settingare are for a GY6. I got numbers of .003 for intake and .004 for exhaust cold. That seem a little tight for me. Can anyone confirm what the clearance is. Thanks again.

my book says .003 intake .005 for exhaust-i set at .005 for both & retorquethe head first

[BuggyMaster]

I've actually tried many different clearances and anything more than .003 on both is too noisy for me.

Ok, those specs are close to mine. I think I will follow yours. Always saver to be a little lose than too tight. What do you have for head bolt torque numbers.

[Pogo]

Then maybe the .003 and .004 are the correct clearances that I got out of my manual. Will decide when I get it apart and check it.

Intake is .003" Exhaust .005" . Remember these are air cooled engines so you want more clearance in the exhaust to keep the valve on seat to cool.

I've found that they get tighter over time, I set both of them at .005 and when it acts like it doesn't want to start easily I know it's time to reset them again.
