This is probably a better question in a thread versus a sticky. But. . .
Sorry if I am stating the obvious, but you should only be reading the oil level with the bike shut off. I does take quite a while for the oil to get back down to the sump. Cold or hot does not make a difference in my book.
I have used a really long and skinny funnel with the fairings on. I can be tricky as it is almost flat, so the pouring is sloooooow. The other thing I use that someone posted around here is an empty toilet bowl cleaner bottle, like Toilet Duck. Just go to the grocery store, find the one with the longest 'neck,' go home and clean your toilets, then clean the bottle well to remove any trace of cleaner, and fill with your favorite oil. The one I have reaches nicely to the fill hole. I cannot drain the entire bottle of oil, but I can get most of it in there without spillage or loosening fasteners.
Have a good one.
