Fuel trouble can start in several places. For carburetor work, fuel delivery, or intake and filter service, use Yamaha Big Bear 350 Carburetors, Fuel Systems & Delivery, or Air Intake & Filters.

A dead battery does not identify the failed part. For battery, starter, stator or pickup-coil work before trail rides, hunting season or work around the property, use Yamaha Big Bear 350 Batteries, Electrical Components, Starters, or Stators & Pickup Coils.

Start with clean, tight cable and ground connections, then match the battery case and terminal orientation or the starter, stator and pickup-coil plugs to the product page.

Top-end work needs matched parts. A Yamaha Big Bear 350 piston or top-end repair belongs in Pistons & Rings or Top End Rebuild Kits, while Engines & Parts and Transmission & Parts cover the larger job.

Match the piston kit or rebuild parts to the engine application and what is included, and ask PirateMX if the product page leaves those details unclear.

Trace the play first. Use Yamaha Big Bear 350 Ball Joints Bearings Bushings for wear at those points, then check Steering Components or Suspension & Steering when movement comes from elsewhere.

With the quad safely supported, move each joint separately and watch where looseness starts before choosing a ball joint, bearing, bushing or steering component.
