Don't know the backroads in that area. But your route might depend on whether you're stopping over in KC specifically, or if you're just wanting to get past it to the Kansas side. Assuming you're taking the Katy Trail from St Louis, Highway-7 NW out of Clinton has a shoulder to ride on. From it, one can catch several highways west, including Highway-2 just south of Harrisonville. Otherwise, check the maps best you can.
