I put those notches in the chain because some asshat engineer at Kawasaki decided that you shouldn't be able to put on or remove the cam chain while the case halves were together! There's a little metal post under the crank sprocket that prevents the chain from being lowered off the sprocket, and I only found that out AFTER I had the whole motor built up to the head! There was no way I was going to rip it all apart again so I put those two small notches in there so I could slide it over the crank sprocket. Then once tension is put on the chain, the sides are pulled up and it can't come off.
