Chain alignment

[Coop]

I dont align chains, I align sprockets. Face to face to insure parallel. You tension chains. So tightening chain and aligning sprockets is a two action process.....for me anyway.

To each his own. My chain connects my sprockets. Yamaha decided to forgo a rear sprocket with a lot of flat area. The flat area is 3/4 in or slightly less. Just enough room to accommodate the laser. So, if the chain goes there, it goes to a sprocket. If the laser shows at the same point near the rear sprocket and in the same position near the front sprocket, I have aligned my sprockets.
