clutch is weak, its luck a thing, some are tight some are loose out of the box. mine GX that came with the bike were ok. the new one i replaced it with slappy slap slap on the 2nd week, even drop the chain and scratch my frame last weekShould I take a link out of the chain? Seems to drop down a gear through the rough downhill sections then changes back up when I get on the gas.
much prefer the type 2.1 clutch of the 11 spd that you can remove the pin, open the cover and tighten it, it does groan with suspension compression for a bit then quiet down as it "wear" in.
