RZR S 900 Cheap clutch mods to gain rpm anywhere? August 27, 2015 Hey guys looking to see if anyone has come up with a way to increase rpms without dropping $300 on a spring and little arms. Probably wasting my time asking but I figure its worth a shot before I drop $300. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
