help suspension setup

[yz250337]

well im a beginner at suspension tuning have owned many bikes but never messed with clickers or anything but i started racing mx last year first full year and im a rear to midpack junior racer not sure what class it would be for usa C class i think but any way i own a 2006 yz 250 and i have been reading about suspension and its supposedly one of the best stock systems out there but so far its miserable for me, i owned a cr125 and that was the bike i learned how to ride on and it was great suspension i learned how to jump i could come up short and it would handle it great but with the yz anytime i come up short it hurts it could be becouse the jumps are much bigger now but i thinks its becouse of how the suspension is set up any way a starting point would be really helpfull or tips really anything i know allmost nothing about suspension?

i weigh 180 in street clothes ride mostly mx but sand and trails to so any help would be appreciated
