Chip, in his post in Rider Technique, brings up a good point: how rear wheel alignment can affect headshake. Those goofy "teeth" that are supposed to aid wheel alignment settings simply do not. A true measurement from swing arm pivot axle to wheel axle, each side, is dead on and keeps the cycle from going down the road 'sideways' like a dog. Calipers that large are pricy.. but this is a critical measurement. Maybe I can borrow one from the plant....hmmm

Probably slightly less precise, I use calipers to measure from the end of the swingarm to the end of the adjuster bracket. Seems to work okay.

I take the chain guard off and eyeball it. Probably the least precise, but I don't have any tracking issues.

I go chain guard-less. I also try to make sure the rear sprocket is running in the center of the chain links. Seems to track fine like that.
As for front end wobble and tire cupping, upgrading to tapered head bearings CURED that!

A great $50.00 investment!

I use an "eyeball" technique as well; I lay a metal straight edge (from a 1' carpenter's square) flat against the sprocket and sight down the edge until the links are parallel to the line of the ruler.

I use one of these. "Goofy teeth" are off by almost whole tooth.

I do use the chain adjuster teeth to get it in the ball park but then switch to the calipers.

I'd heard so much about the alignment marks not being accurate I finally bought a chain alignment tool. You all were right. The tool showed me one side was out about two quarter turns on the adjustment screw.

Yeah! FriarJohn & I agree. I also use a digital caliper to measure but I read from the front end of the adjuster bracket to the front of the axle slot on the swingarm. Then I verify my chinese caliper with a Starrett vernier caliper from the rear of the swingarm to the end of adjustment bracket. This works if you're a bit anal. always spot on.

I use a toothpick and count the spaces between the threads on the adjusting bolts...works great and is accurate, bike tracks true as anything.

Sounds like there's a lot of ways to get it done.

Yes, you are quite right there! Don't forget that regardless of method the reason for the whole thing is quite simple! It is to get the rear wheel to track and follow right behind the front wheel when the bike is moving forward!
