June 4, 200719 yr Hello all, I have a 1983 Honda TL125D This uses a 22 mm Keihin carburettor which has two codes stamped on it. These are PC04J and VB. Can anyone tell me the correct float height? It is 19 mm now, and the bike runs a little rich. Increasing the height to 20 mm will bring the float level. I will try this but does anyone know the height set by the factory? Thanks, Peter.
June 4, 200719 yr Hi Peter, Your float level isn't going to make the bike run a little rich. It only turns on or off the the needle to keep the bowl full without having it too full. What is the bike doing now? Fouling plugs?
