We are running a 14t Noram heavy shoe clutch red springs with a 59 rear sprocket on a flat usually fairly dry 1/10th oval. We run a restricted Subaru EX27 spec motor in a QRC winged kart
All we can get is about 2700rpm out of it, we moved up to a 63 rear sprocket ran the same line and no change in rpm, tach barely moved from going into the corner and coming out and down the straight. tach is working, it takes off at about 1800rpm. i did just change the shoe settings from what looked like a more gradual setting to a more aggressive setting. Any ideas, clutch is brand new
Thanks
