i'm a light weight fully dressed in daily clothes about 140lbs (shoes already subtracted) What spring rates do i need? i know lighter, but i need exact spring rates here. i'm a middle of the road Novice rider, but i feel if i could get my ass end to stop bouncing i could go faster. i have tooled with the adjuster a lot, but still need help. Now suppose i did get new springs, would i still need to have everything re-valved? please advise?
