JJ1 Posted March 24, 2010 I bought a 2007 yz450f. the guy had smart performance do a supsension job on it. New valves, springs etc. and a larger rear spring. He was 220 and I am only 170. It is too stiff for me. Is there anything I can do to the existing to soften it up without having to redo the entire suspension. He did give me the stock rear spring. Could I just put that back on or would that throw the whole thing out of balance. Any ideas would be helpful. 👍 Share this post Link to post Share on other sites
