The dimension should be between 88.9 and 90.2 mm.

However, the slack is still excessive and could be the only source of the noises.
Which brings me to another question, where in the cam path does it slap to give that sound? is it at the top chain guide? i am assuming so because thats where the noise is the loudest.

Anything regarding the valve spring?

And most importantly, why is the rocker screw bottoming out?
