Once the tire is completely on the rim, I just spray the beads good with Windex. They seat perfectly every time. Anything slippery will work, but I would avoid petroleum based products. They will deteriorate rubber over time. I have used STP Son of a Gun to mount tires with,(damn that stuff is slippery) but still use Windex to seat the beads. Make sure the tire is not touching the ground or floor. Either support the wheel by the axle, or lay it on it's side, so the tire is not touching anything.
If you can't get the bead to seal well enough to hold air, I use a variation of flitecontrol's procedure, which I have never had to use on motorcycle tires, but it works great on car and ATV tires. Instead or rope around the tire, I use a ratchet tie down, like I use to tie down my dirt bike with. You can put a LOT of pressure on the tire tread with one of those, forcing the bead against the rim. Jerry.
