Personally, I would go with .06 mm intake and .10 mm exhaust. If it's off either way by .01 mm, not a big deal.
In our experience on this forum with Chinese bikes, very often they come from the factory with gaps that are far too tight. Like when they are assembling the motor, they have only one .02 mm feeler gauge and just set everything with that. So what happens is that as the motor heats up, the valve stems lengthen, compression is lost because the valve no longer closes completely, and the bike stops running until it cools off. Very common. The exhaust valve is the bigger problem with overheating, as it only ever sees the hot burnt gases going past it. The intake valve only sees cool air and fuel entering the chamber, so is usually not such an issue. But too tight would mean it does not fully seat either; and too loose would mean it does not ever fully open, for good breathing.
I looked up what that bike was and found a review article. Very nice looking retro bike.
