YAMAHA issued a recall on the VMAX (VMX17) model

On certain motorcycles, there could be excessive electrical resistance in the ground wire for the Accelerator Position Sensor (APS) and Throttle Position Sensor (TPS) due to an insufficiently crimped connection. Excessive resistance can cause incorrect signals to be sent to the Engine Control Unit (ECU), which could lead to unstable engine idle speed and/or keep idle speed from falling below about 3000 rpm when the throttle is released, preventing a proper return to idle that could result in loss of control and an crash causing personal injury or death. Correction: Dealers will install an additional sub-lead wire to bypasses the problem area of the wire harness (which will prevent the excessive resistance concern).
