Hi,
difficult to match exact model. However a typical small engine will run about 0.06mm inlet and 0.10mm exhaust. Measured when the engine is cold. Make sure the clearance is at least the figures quoted and not a tight fit. Insufficient clearance can result in burnt valves, excess clearance results in extra rattle.
The figures above will allow you use the bike, ideally continue your search for exact values.
