2019 PW50 - Pros & Cons

Strengths

  • Accessible seat height: At 485 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.

Considerations

  • Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.

Owner Experiences & Common Issues

Carburetor maintenance

Carburetors on the 2019 Yamaha PW50 benefit from a clean and re-jet if the bike has been stored, run on stale fuel, or modified with an aftermarket exhaust. Owners frequently mention that fresh jets and float needle clips transforms throttle response from flat to crisp.

PW50 - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2019 Yamaha PW50, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained PW50 should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any PW50. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the PW50 has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
