Anyone know the squish band specs for an 02 ZR 800 EFI?

Thanks.

.066? working off memory... some '01 tech manuals had a misprint that said .061 I think. Many came through .0720 - .0780. 060 worked for me...

Dont go to low if your shaving your heads though. If you dont have enough squsih band it dont matter what octane fuel you run eventually the top edge of your pistons can break off, that makes a big mess. It happened to me.

Not looking to whack a chunk of aluminum off. I have not measured my cylinders yet, but I want it as low to the bottom of factory spec and/or slightly lower. Did some engine mods and just want to be sure everything is as good and tight as I can get it.
