New bike/fazer owner, proper way to go about the initial service?

I'm still having problems with the muffler. I tried to bend it out from the frame but there is too much leeway in the bracket mount so it keeps going back and rubbing the swingarm.

I think the exhaust is original, but it is painted black and there is a piece of rubber in between the muffler/metal holding it. Probably put there to conserve the paint.

It is extremely hard to fit it if I take it off. How is it with you guys?
