Fork tops out- Adjustment or mechanism issue?

I notice when I lift the front of my bike to jump or go over obstacles (compress then rebound) my fork tops out, I can feel it extending to its max and it makes a noise that indicates it has topped out. Is this normal? I can't imagine topping out being good for the fork, same goes for bottoming out but that's not the issue right now. May be I have not set my sag properly- possibly not enough sag? I'm running 15% sag on my 100mm RockShox Tora SL = 15mm sag. Any help is much appreciated!

I would've thought the Tora would top-out silently as with other good quality forks. Adding a little bit more rebound damping should minimize it...

It's not really a loud noise when it tops off, I feel it more than I hear it but I just wanted to know if it's normal for it to top off everytime I compress and rebound.

Wouldn't adding more rebound damping cause it to top off even more since it forces the shock to spring back faster?

^ Adding rebound damping slows down the fork more when it extends back out from being compressed.

BTW, it's normal to feel a bit of "top-out", obviously to a lesser extent with forks that have negative springs or chambers... but it will still be there. The combined weight of the wheel/tire/brakes/fork slider/axle has inertia and when that movement stops you will feel it, clunk or no clunk.

I will try and slow down the rebound and see if that helps.

I can't imagine constant top off being good for a shock. Feel like it would eventually rip the fork apart.
