Why does my Polaris 550 IQ 136 2013 engine RPM fluctuate erratically?
- HHayley GregoryAug 7, 2025
If your Polaris Offroad Vehicle's engine RPM fluctuates erratically during acceleration or when the load changes, it could be due to a drive clutch binding. To resolve this, have your dealer disassemble the drive clutch to inspect the shift weights for wear and ensure they operate freely. Another potential cause is a driven clutch malfunction. In this case, your dealer should replace the ramp buttons and rollers.
