A nonstock mod I would recommend since it is apart is, the small oring over the crank against the seal.This helps seal the crankcase better.Here's the write up, from Mr. Schmidt, Jseng1.The only real (very rare) problem wet sumping can cause is blowing out the crank main seal. You can avoid that problem by installing a 1-1/8" ID 3/32 wall viton oring between the primary sprocket and the main seal. Its a #122 oring and you can get them for cheap at suppliers like Mcmaster Carr. Wet sumping also makes it a little harder to kick over the motor but its not much of a problem on kirk start 750s or 850 Mk3s with electric start.Along with the o ring, I would replace the crank seal... Just because.... after the little sanding/polish recommended by Mr. Marsh.
