I’m curious what the stock head gasket thickness is for a kdx220. I am going to try to have a copper headgasket cut for my 220. Thanks

surprised nobody was able to reply to this given a few posts ago was about squish band and compression, from memory its 0.20mm
but before making any head gaskets i would check your squish clearance first then you can customize it

You may want to check if the gasket you get has been annealed. Being rolled to that thickness, the copper could have become work hardened. If so, it won't deform to comply with the joint faces and seal the joint.
You may be able to anneal it yourself by heating to a glowing red color, but I'd be concerned about warpage.
Contrary to common belief and often published advice, quenching in water or just letting the copper air cool has no effect on the annealing process. Its the heating that does the annealing.

I think a lot of the guys on here have heard enough from me, and I wouldn’t blame ‘em. Just took my 1991 200 for a ride and it was awesome, just having such bad luck with this 220. Thanks for the info

Thanks for the info. I’ll see if they can make it for me, and make sure to ask if it is annealed.
