CAN-AM OUTLANDER 850 Jerky Acceleration

CVT Drive Belt
The most common cause of jerky acceleration in CVT-driven ATVs is a 'burnt' belt with localized narrowing or flat spots. These irregularities cause inconsistent friction between the belt and the clutch sheaves during the engagement cycle. Replacing the belt restores a uniform contact surface, ensuring smooth power transfer as the primary clutch closes.

Primary Clutch Maintenance Kit
Internal components of the primary clutch, specifically the rollers and sliding buttons, can wear down or become fouled with belt dust. This increases mechanical 'stiction,' preventing the clutch from expanding smoothly in response to centrifugal force. This kit replaces the high-wear items that facilitate the linear movement of the clutch plates.

Pedal Position Sensor (PPS)
Modern Outlanders utilize an Intelligent Throttle Control (iTC) system; if the PPS (the electronic throttle) sends an erratic or 'noisy' signal to the ECU, the engine may surge or stutter. While less common than mechanical belt wear for 'jerky' complaints, a failing sensor can manifest as inconsistent acceleration if the potentiometer tracks are degraded.
