About the Yamaha BW350
Oil-service parts and replacement controls for the BW350.
Yamaha’s model archive includes the BW350 in its Big Wheel-era range. The service choices here focus on the engine’s oil-filter arrangement, valve-stem sealing and handlebar controls. Compare the filter with the correct engine specification and identify both lever perches, particularly when earlier repairs have changed the original controls. Yamaha BW350 model archive.
Check engine service parts against the installed pieces
Compare the oil filter’s construction and sealing faces with the correct application before changing it. Valve-stem seals address a particular engine sealing point, so investigate the source of oil use or smoke before choosing an engine repair. For a bent or broken lever, inspect the perch and pivot as well as the lever itself.
