coolant

I'll be darned if I see anything in the small white plastic window that is supposedly used to view the cooling fluid level. Is there some magic trick?

I noticed my bike was overheating but thought nothing of it. I rode around with my bike continually getting hotter as time went on (especially during idle). It's important to note here that I live in central Texas and Summer had hit, so my bike(s) getting hotter during cruise is normal...
