There's not much point in venting the airbox unless you also rejet.

is it really worth cuting and releting?

Just take the lid off--then you can put it back on if you want. A main jet change takes about 2 minutes (with practice). Adjusting the fuel screw is a little tougher but not too bad. It's likely you won't have to mess with the needle.
