YZ-100 won't rev
My friend picked up an old YZ-100 on the weekend. It is roughly 1979/80 model. I cleaned the carb and air filter and it starts and runs ok but will not rev up. I pulled the lid off of the air box and it seemed to cure it. Tried pulling the silencer with the lid on airbox (thought maybe the silencer was plugged) and it did not rev up. Does anyone have any other suggestions? Also does anyone know what size main jet should be installed in this bike?
