Valve Checking: Metric Feeler Gauges? Any with our measurements?

I am going to be checking my valves on my new to me Vrod soon because i have had multiple people listen to the bike and tell me it sounds like a loose push rod tick aka loose valves even tho i only have 4800 miles on the bike, when going over the manual i for the life of me out of the 8 different feeler gauge sets i have dont have any specific to the sizes this bike calls for, so i stopped in at Harley to ask for price on the HD Feeler gauge listed in the book since its on my way home and they told me its a dealer only tool, not to be sold to public.... sigh

Has anyone found any aftermarket ones that meet the criteria we need?
