from the last picture it looks like the bike is a tooth off on the right side i found out a trick fixing the timing on my bike if you remove the spark plug and stick something long like a wooden dowel rod in the hole that the spark plug sits in, it will rest on the top of the piston and then when you turn the shaft watch the rod and see when it stops at the top then check your timing this is not the most accurate way to do it but it can help determine which line is the one you should line up with
