If you can install the barnett clutch springs with your stock clutch plates, do it when your plates are still fresh. My stock clutch plates/springs lasted a while and took a bit of abuse with the big bore before tiring out. The ebc clutch springs didn't last long at all. I had to get the barnett springs since the ebc clutch kit springs would slip after shifting into third. Now wheelies aren't a problem after 3rd gear. Catch it early and the oem plates will last.
