New J01 edge 2.0 upgrade question

With the hop slider all the way forward it only shoots about 20 meters then drops all the way back only about 5meters. I’m using a 11.1v battery and have bought a new hop and nub anything else I should change? I’m in Japan so I have to stay under .98j. Also can anyone recommend a disassembly video I tried taking it apart but couldn’t get the inner barrel out.
