Elfmaze,
A three hour round-trip sounds like about 200 miles, which is really not that long for a trip. You don't say much about the type of bike you came from or what you have done to make your C-14 fit you. The C-14 has some ergonomic issues that take some getting used to. Have you added risers or tank grips? Both of these should help with your seating position on the bike.
You will likely need a new seat if you are going to do 400+ miles per day trips. I average 200-300 miles per day, have 16K on my bike and still have the stock seat
