alright heres how you fix the stock pro headset.
i figured it out and now my scooter is like a rock.
take your bars off.
loosedn the lock nut so its out of the way.
tighten and loosen the adjustable race until its tight enough to keep the fork on solid but not so tight that it doesnt spin.
hold the adjustable race with a wrench or whatever and use another wrench to tighten the locknut.
keep the adjustable race just like how i said,not to tight but not to loose,and the locknut should be really really tight to ''lock'' everything in place.
and there yah go
