Mine looked fine when I recently did the cam chain tensioner and more recently the new BBK. I have around 5700 miles on the stocker.

I replaced mind and they both have about 1K miles on the chain with the Koso cam chain tension "metal gear wheel" but I will soon change to the Yuminashi flat chain and their cam chain tensioner system which will remove the center cam guide wheel inside the cylinder wall.

I placed an order earlier this morning to replace both guide rollers, chain, tensioner spring and rod head. Since I'll be removing the NEO chain here shortly I figured I'd get a new chain for the upcoming build rather than using the stock one that had 5k miles on it.
