nope youre good to go, thats the stock carrier on there, just bolt up the stock swingarm now, and run a line to the rear brake caliper, they work better with fluid pumping to them
before bolting up the stock swingarm, you may as well order a set of bearings for it and put them in while its off ,seach on ebay for "banshee swingarm bearings" should be around $20+ or so for the set of 2
those are the stock banshee dunlops, they suck even when brand new.. you need some MEATS! my 2 personal favs are holeshot GNCC and razr2, thats a whole nother thread and debate in itself though, really depends on your needs and what type of terrain you are riding.. whatever you do, dont buy any kendas , no matter what any tanned and jacked men try to tell you
aside from that, i would say your biggest concern should be how it runs , if you are clutching to bring the revs up now, it will only get worse once you put some real tires on with some tread, they will be grabbing 10 times more and putting much more of a load on the motor, if it cant get into the powerband now, it will be even worse with new tires
