Welcome to the forum and hope you enjoy the bike....
If I were you, I would probably try a straight edge of steel/wood (X 2) along the wheels to check the alignment.
They do this in the MOT station and it can show mis aligned areas- Frame, swing arm, forks.Someone needs to be sat on the bike with the wheels on the floor and pointing dead ahead.
You have to allow for the different tyre widths, but once you know the wheels are in alignment (as the gap is the same size at either side of the front tyre) you could measure from the bar end back to the tank retaining nut under the seat and see if left and right are equal- like a triangle.If they aren't equal then you need to get them equal by correcting the fault,
either bent h/bars, twisted yokes top and bottom or fork legs.
I wouldn't use heat and start pulling stuff straight.I used to do, but that was on dirt bikes.
If you get stuck, you could take it back to your supplying dealer OR go to an MOT station and ask them to sort it out. Failing that, insurance claim...
