Fitted my new JD Jetting supplied PWK 38 Air Striker Carb to my 1985 KX500B1,
Simple bolt on replacement installation.
Bike started second kick, and runs much better, HOWEVER the new carb has the controls / adjustments on the left side, hidden completely behind the airbox! This is a major problem and I am gutted as it is SO MUCH better than old Mikuni TM40.
