These springs are what keep the clutch plates clamped together so power gets from the engine to the gearbox without the clutch slipping under load. Over time or with heat and use, clutch springs can lose tension, which shows up as a clutch that slips or grabs unevenly. If your clutch feels soft or the bike hesitates to pull cleanly under power, worn springs are one of the first things worth checking.
Our catalog record for this part spans appearances from 1960 through 1974, but as always, check your parts book or give us a call before ordering to make sure this matches what your particular clutch assembly calls for.
