leave the rear shock alone as you hop the bike not the bike bounce you around. If youre unable to do hopping then you need to learn the art of it. My friend years ago buggered around with his beta strippy and it cost some to get it back to standard setting as in yes it hopped but crap in sections with rocks, pebbles even. Take what you might get in advice from fathers with a pinch of salt as ive heard all sorts of crap to be honest. Ask an adult inter or expert and im sure you ll get the right reply.
I learnt but riding on falt land and made a circle to which i made it smaller and smaller and likewise with a figure of eight.
Best of luck
