T-MAP Sensor Wire Repair Harness
The factory harness is known to be too short and brittle, leading to internal wire fractures from engine harmonics. This causes intermittent sensor feedback to the ECU, resulting in rapid fueling adjustments that create a 'sputtering' or 'jerky' sensation during acceleration. This kit provides a pigtail with higher-strand-count wire to resist vibration fatigue.

CONF
CVT Drive Belt
Heat-induced glazing of the belt's sidewalls reduces friction against the clutch sheaves. As torque increases during acceleration, the belt momentarily slips and then catches, creating a physical shudder or jerky movement. Replacing the belt restores the required static friction for smooth engagement.

Primary Clutch Spring
Mechanical fatigue of the primary clutch spring alters the rate of engagement. If the spring has lost its tension (sacked out), the drive clutch may engage the belt at an incorrect RPM, causing the machine to 'lurch' or jerk forward rather than transitioning smoothly through the CVT ratio.
