hi Ken,i bought a stm slipper cluthch for 450r 04 motard off you a couple of years ago # 0F3OR230B1100MX n am very happy with. ive have somehow broken the secondary spring rated 50kg #0F3SR540B140006. thing bout replacing it with a 40kg spring now. wots your thoughts?
judging by the clutch part # i think the springs mite be rated for MX use, do you know wot the SM spring rates are for these cluthchs? the primary spring i have is 160kg.
thanks
Jason.
