Yeh, it's a really easy job.
Just make sure the front ends off the ground but also the front wheel is supported to stop the forks leaning forwards and stressing the lower clamp once the upper is removed. Also wedge the wheel so it stays facing forwards (just makes it easier to work with).
Bars off, undo the fork clamps & stem nut, old top yoke off, swap the ignition barrel over, reassemble.
That's about the size of it I think.
It's a shame it happened but it could have much worse.
