tbpmusic said:FLOAT LEVELS - CB/CL450
Another critical issue to run properly is float levels in your carbs.
They’re set at 20mm on a CB/CL450. This procedure can be used for most old Hondas (use measurements to suit your bike).
I always set them off-bike, with real gas running through them (it can get a little messy).
Make yourself a tool from an old credit card, use these dimensions for a 450 :::
Then, hook up a fuel line and use the gauge like this -
s you push up on the float with the gauge, the gas should just shut off when the sides of the gauge contact the carb body (in the notches - you'll see what I mean).
Be sure to hold the carb vertical.
now i am sure i had the tool.....i remember the 20mm spec.
