Don't depend on the marks on the swingarm to get things lined up right. I have a Motion Pro gauge I use now but I have used cord before . Pull the tow frame covers off the left and right side that cover the swingarm bolt and measure from the center of the bolt the the center of the rear axle.
Here's the tool I have it makes things faster and easier. I think I gave about $20.00 for it. It clamps to the rear sprocket and you simply sight down the chain and adjust until there are parallel.
