ALWAYS pull the bike to the side of the trail, smile, wave, and if a horse is involved SHUT DOWN THE MOTOR. Nothing worse than a guy who may pull the bike to the side of the trail, smile, wave, and sits there blipping his throttle...
Oh, and when you pass a vehicle, you would be AMAZED how little throttle it takes to throw rocks into the windshield of the person you are passing. Or... face of the person on that hated ATV. If you can accelerate BEFORE you pass, then just roll past with the clutch held in, all the better.
