Too loose = bad, too tight = worse. If you chain is loose, you will hear it slapping around. If its too tight, you may not hear anything or some type of popping. Over tightened chains can mess your shit up. They can wear out or break a counter shaft in little or no time at all.
First of all, buy a steel, millimeter ruler to check the alignment with. The tick marks on the swingarm are not precise enough to get the alignment right. Next, loosen everything up and re-adjust the chain so that you have the correct amount of slack, and a good alignment. Do each side, a little at a time, and alternate back and forth. If you go too far and the chain is too tight, loosen the adjustment nuts up, knock the wheel forward, and start again. Now, tighten the axle nut down and test ride it.

I think part of the problem was the fact that I was taking the axle nut completely off. When tightening it all back up this straitened the axle shaft out inside the adjustment block and tightened the chain further then I planned for.
I am outside working on it and may just wait till tomorrow so that I can get a good ruler and get this shit right. This sucks. |

Also, the millimeter specific metal ruler is better than the notch marks on the axle, but the swingarm itself might be off slightly, not to mention whatever you are measuring it against, the best way to make sure the chain is right is to use a chain alignment tool, which can be had pretty cheaply ($10?) from any good dealership. |

When you tighten the axle nut it will affect the chain. Something that none of your friends have mentioned is that you need to find the "tight spot" on your chain. Due to imperfections in manufacturing and installation,you are bound to have a spot in the rotation of the rim where the chain is the tightest. You need to find that spot and take your measurements from that point. You should have about 3/4" at the tightest point,with the bike on the kickstand and the axle torqued.

You should also check the straightness of the rear axle. A great way to do it is to measure from the swingarm pivit bolt to the rear axle... like this.
