Jim - many thanks! Didn't want to use my brake and find nothing there! Going in for a service next week also thanks again

I have a '99 Yamaha YZF Thundercat and use it to comute to work. This evening when I got home, I noticed that there was a small amount of green lube leaking from the rear of three overflow tubes on the off side of the bike - sorry to be vague but i have not had the bike long! It was only two or three drops and has now stopped. I have not noticed this before and it concerns me a little - I cannot find what these over flow tubes relate to in the manual. Is this normal or should i get it looked at?? I travel around 16 miles from work which is quite a quick ride. Thanks in advance!!!
