Himalayan 450 pulling to the right since day one. What could be the reason?

Hi guys,
My Himalayan 450 has been pulling to the right since the day I bought it. It has been there from day one. I’ve done around 13k KM on the bike and did my 4th service today.
I’ve already tried changing few things
>The handlebar bushes
>Got the spoke wheels trued
>Got the wheel alignment checked
But the bike still pulls to the right.

One thing I’m confused about is the service bill. They have mentioned front and rear spokes balancing, but they didn’t actually put the wheels on a balancing machine or computer or add any weights.
From what I understand, wheel balancing usually means checking the wheel and tyre for weight imbalance and adding weights if needed, while truing is about correcting the rim by adjusting the spoke tension. Please correct me if I’m wrong.
The SC also told me that if the issue is still there, I’ll have to leave the bike with them for around 3 days. They said they want to check the USD forks by swapping them with the forks from another Himalayan 450 to see if that makes any difference.
Has anyone else faced this right-side pulling issue on the H450? What else could cause it?
