I had class all day today and this morning when I rode to campus it was a little overcast but I kept my fingers crossed. Well as my luck would have it by the time I was finished up with class around 5:30pm it was pouring. When I first started the bike up it seemed like it had a little bit of hesitation to run. I gave it some throttle right after starting it and it was choking a little, but a few moments later all was well. This normal?
