Seating a stuck bead

[jjrider]

I have changed lots of auto , truck and atv tires in the past but this was my first actual motorcycle tire that I have done. The tube part is kind of new( I remember doing bicycle tires as a kid so I remember the do'es and don'ts). I got a container of baby powder(that's what I remember using and hearing being used by some) and sprinkled it all over the tube and inside the tire, I didn't go overboard though, and put everything together, no pinched tube, made sure to line up the stem without force, made sure the tube wasn't twisted.
Anyway got to airing it up(this is a front tire), and went up to 30lbs,played with the beads to try and help seating, then slowly added 5 lbs more and repeat. (the tire says 36psi max) I stopped at 45-50lbs and one area still didn't come up to full seat yet. I even aired down and sprinkled more powder around the beads and put air back in it up to the 48ish lbs and still not fully seated.

Now with car tires I use bead soap and keep adding air till they go, same with atv( only a bit more carefull on how much air). With the tube and aluminum rims I didn't want to use the soap(corrosion and the powder for tube movement), so do I keep adding a few lbs and messaging, then add ect.. till it finally goes or do I need to use a different lube or procedure?
Thanks
