Frequently Asked Questions
How many 42mm round pod filters are needed for the compatible Honda CB models?
One 42mm round pod filter is included. The listed CB650, CB750K, and CB750F models use four carburetors, so four filters are required to equip the complete carburetor rack.
What should be measured before ordering 42mm Honda CB pod filters?
Measure the outside diameter of the carburetor's air inlet. The filter's 42mm mounting size must match that outside diameter; it does not refer to carburetor bore size.
Do round pod filters require carburetor adjustment on a CB650 or CB750?
Pod filters change intake restriction compared with the original airbox. Check carburetor jetting, mixture, synchronization, and throttle response after installation instead of assuming the stock settings will remain correct.
