You gotta fab up a little bracket to act as a new stopper for the centerstand. No big deal, tin snips and 5$ worth of metal strap from the hardware aisle at home depot. You can even get the one with the holes punched in it already. If you get a thicker strap use a hacksaw and file, the thicker strap won't bend over time.
These bikes always feel hot, like flybox said, its aircooled. If you pull the plugs and they are white then yeah, that's not good. If you go from waterpumper to aircooled it will seem hot tho
Get yourself a new speedo cable, probably snapped internally. Motion pro makes nicer ones now, still only like 15$. I don't go for OEM on those kinda cables
