Am I not being anal enough, or am I naive? I just use the marks on the swingarm. The chain has some slop in it, so it doesn't have to be dead nuts plum to anything. And as far as alignment from the front to rear wheel, these bikes have knobby tires, and are used on the dirt, so it's not like we're going top speed on asphalt all the time, so the tires are constanly slipping and sliding around, so I don't see the point in the wheels having to be perfectly in line. Maybe I'm missing something, but I want to ride, not wrench.
