check/adjust valve clearances???

I was wondering where can I get info on how to check the valve clearance. I have about 1100 miles on my 06 c50 and would just like to check it for peace of mind. I'm guessing I have to take the tank off, but theres nothing in the owners manual about valve checks...thanks for any help

ok nevermind..i see where the access is....thanks

Well I tried doin it myself....not so good.  It ticked like crazy, too loose.  Finally took it to a dealer and they did it right for 125 bucks.  Must need a special feeler gauge to get in the tight space.
