how to set Yamaha pw80 carburetor
Not shure

yes they are all the same
well a pw80 goes 74kph and a kx65 goes 110kph
The correct float height setting for the Yamaha PW80 is typically around 18-20 mm when measured from the carburetor body to the bottom of the float. To set this, ensure the carburetor is held upright and adjust the float tang until the desired height is achieved. It's important to check the service manual for specific guidelines, as variations may exist based on model year or modifications. Proper float height ensures optimal fuel delivery and engine performance.
All Yamaha PW80 s have 3 semi automatic gears ( no clutch lever etc )
It all depends on condition, if its a nice clean pw80 about 800-1200. hope this helped
They are pretty simple, wiring wise. Here is a diagram from a 2001. http://www.weeksmotorcycle.com/pw80-wiring-diagrams.html
