What's the difference? Airfilter cases

[deltarider]

Does any of you know what is the difference between the airfilter case* 17313-323-030 and 17313-323-040 mounted on the CB500 and CB500K1-2 resp.?
* CASE , AIR CLEANER ELEMENT SEAL in Honda speak.

Different manufacture, maybe

I've got both (apparently) and can't see a difference. I notice that the air filter element is also different. 17210-323-020 to 17210-323-030 for K1, K2. But presumably backwards compatible.

IIRC that has to do with that handy lip to remove the filter element.

Could be.
Do both have a little drainhole in the bottom?

Both mine do.

Somebody told me (probably Bryan or Ash) that the last three digits changed for alternate suppliers (of the same part).
