If they are the same then you should be fine. Put the bike up on a rear stand and spin the tire. If it stops really quickly and feels like it is a little more difficult to spin than it might need more adjustment. Also when you ride, if when you let off the throttle and it feels like the bike slows down faster than normal it could be out of adjustment. I had mine out of alignment once and found out that way. I was moving and had all my tools already gone on the moving truck so I took it to the stealership and they screwed it up, but I fixed it soon enough and they did it for free.
