but I think the internals need a tweak.
What makes you think that?
On your fork you have…
Low Speed compress adjust (the big blue dial), low speed rebound (the big red knob), air pressure, air volume (the air spacers, grey or Reddy orange).
What you want to do is set sag correctly first (Google this, as there’s loads of videos on it). 0.5/10 for difficulty.
Your low speed compression will adjust how quickly the fork can compress in response to trail chatter. It effectively holds the fork up in its travel. So if you find yourself with a wallowy fork, you can add some low speed compression.
Your low speed rebound has a similar effect, you generally want to set it as fast as you can without it bucking you off the bike.
Volume adjusters, they adjust how much force is needed on the fork to compress it.
If you feel like the fork feels good for small bumps, but blows through the travel too quickly on bigger bumps – pop a volume spacer in. Again loads of videos how to do this. 1/10 for difficulty.
