4) Torquing of Engine foundation bolts and Steering head and T bolts/nuts.
5) Try replacing the entire Front steering assembly which includes the front forks the two T brackets and the steering head assembly with a substitute and check. If it repeats its the steering head to the chassis frame welds at fault.
6) Check front disc brake mounting and any crack in the front lower suspension arms.
7) Handle bar mounting bolts, torquing and any cracks on the top T bracket.

+1 . I've cracked the front fork due my penchant for hard braking and the plentiful potholes of that era didn't help - it was a Bajaj Sunny however.

Also, check for bent fork tubes.

I recently started facing this issue again.... My bike's handle suddenly becomes stiff as soon as I pass over a pothole and it starts feeling like the bike will sway left and right due to this stiffness. It stays like that for about 2-3 minutes and goes away and the handle behaves well till I go over another pothole.

I checked by bike by keeping it on centre-stand and turning the handle left and right and I hear a very faint screeching sound when I turn the handle right, otherwise the movement is free and doesn't seems like it's stiff.

Like many suggested this could be a problem with the cone set or front forks. Will have to get it checked soon. By the way my bike is a 2007 model Honda Unicorn. I faced this issue initially when the bike was new but the problem was rectified by Pratul Honda's service centre.

Check the Handle bar mounting bolts or the ball bearings. Might need some replacement.

Also this can happen due to careless workmanship.
