For the leaning, are you saying with the engine off it's level but when it's running it leans, or it just leans all the time?
For the pulling to the right, do you just need to steer the handlebars left to keep it going straight or is it actually pulling hard right no matter what? If it's just handlebar alignment there is a procedure for my 2024 but I'm not sure it's the same for your 2015. You have to remove the small top cover just forward of the console (two screws), pull the cable lock forward (toward the front of the machine) and turn the knob. For pulling right, turn the knob counter-clockwise as you face the rear of the machine, one turn at a time between test rides. Hoping it's that simple for you but please post back if you've figured it out.
