HPP adjustment
You want some preload on that tiny spring!
-----> The tip of that tiny spring where the yellow arrow points to needs to have a small gap to that arm (preload!!). If it doesn't have this gap you need to loosen the allen bolt above (arrow), and while pushing on that arm to have the valve fully closed you can actually push the spring a little more to have it opened. Now thighten the allen bolt and it should leave that preload as described. Do it on both sides! There should be absolutely no play in the valves.
