She now sports a loud and light set of Leovince cans, a DNA stage 2 filter and one of WB's tail tidys. Now my limited technical knowledge suggests that with the cans and air filter installed the bike will suck in and blow out more air, thus making her run leaner than stock. Will the lambda sensor adjust this automatically?

I think it will, but don't fancy having to replace pistons and valves if it doesn't! There is no money left on the kitty for other mods just at the moment.

Congrats!

Well, your not far wrong! Your bike will indeed suck and blow more. The lambda sensor is a thin band sensor, in that it will only detect and adjust to a certain amount. However! It will still only run adjust to the standard XT fuel map which is lean anyway for emission purposes.

A fuel mod would be ideal to help richen the circuit up a tad.

Ultimately, a PCV and auto tune will sort it right out.

I shall purchase an autotune myself in the next few months
