Carb syncing

[Pauarc]

I have just read this in a workshop manual that you should sync carb’s with the air filter off this is from a Honda shop manual on the cb750k does it sound right any one do it this way

You can do it either way but as a carb sync is usually done as part of a service, the filter is usually out anyway. But, if you're doing it with the air filter in, it must be very clean, ie, a new filter.
