For one thing, the rear fender is wider and shaped differently on one side than the other, which will throw the look off.
The rear wheel is aligned when the rear sprocket points DIRECTLY at the front sprocket. This is the most important thing to accomplish in aligning the rear, and the straight edge method I laid out is the most accurate way of getting there. By that method, an error of .5mm at the axle block will show up as 2mm or more at the front sprocket, so you can find the smallest discrepancy.
The other thing is that if you were to remove your forks and hold the frame up with a tube running through the steering head, the rear tire should be pointing right at that tube. If your wheel is still centered correct over the hub, and the frame is straight, it will be.
Well,i have a few more days before i get the suspension back so i'll have time to get it corrected.Thanks for the info.By the way i wonder if anyone makes a device to check straightness.By the way you suggested you would think someone would have made some kind of bar that would attach to the rear sprocket to give you proper allignment.
