Chain Tightening

[billoyd]

Trick question? Without any marks on the swingarm or axle, what is the best way to adjust the chain?

There's marks in there,just look inside the recessed area that the adjuster blocks fit into.Use a flashlight,it's easier that way for me.

Three different ways:

Site down the chain method.
From behind the bike, look down the line of the drive chain to see that it is aligned with the rear sprocket and front sprocket and the chain is stright when taught.

Site down the line of the front and rear tires method.
From the front of the bike, look down the side of the front tire to the rear tire. Notice how much of the rear tire surface that would contact the ground can be seen. The amount should be the same on both sides when the front wheel is striaght foward.

Tape measure method.
Measure from swing arm pivot point to axle. Should be the same.

Wrap a string around the back of your rim. Leave enough slack to run it up to the front wheel on both sides. Attach the string to two stationary objects just ahead of the front wheel like jackstands. Bring the jackstands together untill the string is touching both sides of the rear rim. Now measure how far each side is from the front rim. When the string is equadistant from both sides of the front rim, your rear is aligned properly.

I used two dowels and put one through the swingarm pivot and the other through the rear axle and measure to each in mm to see if they are even.
