if in the future you are planning on building your motor then i would go with toomey t5's, if your gonna keep the motor untouched then go with the toomey t6's. a longer swing arm isnt needed untill you start building your motor, and suspension really isnt needed unless your tired of gettin beat up from rough terrain. also if you like ridin in the dunes (sand dunes anyway) then i would buy a set of 10 paddle haulers and some sort of front sand tire. oh, and dont forget to re-jet your bike after adding the k&n and pipes. also, nerf bars are only needed if you ride in tight trails with tree stump and such pokin out of the ground.
