Valves tapping...?

[ArizonaKev]

So I changed my oil and filter this weekend, put in a stock oild filter and some Valvoline 10W40 cycle specific oil. Made sure it was filled to the proper level and all. Funny thing is, today, riding home from work (when it was much hotter, i.e. 103 degrees) I noticed that it seemed to be tapping a little more than normal - what sounded to me like valves tapping.

My question is - is it normal for GZ's o sound like there is a little bit of tapping, simply because it is an overhead cam and we are so close to the motor? (I haven't ridden a bike for a number of years). I guess it seemed a little weird that it would actually be a little louder after having changed the oil and all. And I made sure it is filled to the right level, checked here and the service manual to be sure.

My bike has 13,000 miles on it, and I bought it about a month-and-a-half ago with 12,000 on it. It appeared to have been very well maintained. Am I being a little overly paranoid about this, or might it need a valve adjustment or something?

As always, all advice and tips are appreciated. Stay cool all - Lord knows I'm tryin'!
