Yes, part #12. The Cam chain rides against that and they do wear.
As noted above, the chain IS stretched, no other way the cam to crank can be off that much...
And with 40K miles, it's not surprising...
My last '05, KLR 250 (Much longer chain), was stretched at 28,000 miles and needed replacement. I was getting some rattle as the CCT was fully extended and barely keeping it taught. Cam chain is behind the balancer' chain. Much more difficult to replace than the FZ, Stator cover, rotor, RS cover, WP, balancer gears, etc need to be removed..
With the new chain in and the CCT extended(before installation). Prior, the CCT was about flush with the block EXTENDED:
