later down the track u might wanna make it go faster, but i'd stick with the cosmetic things, to make it easier to ride on first. start by replacing the fork oil. u may want soft, so go 10-15weight oil, u m,ay wanna go stiff so go 20-25weight oil. it all depends on ur weight. and u'll probably end up bending/stuffing the seal in ur rear shock, so buy a nice DNM one. some ppl like fastace, some dont. all personal pref. and did those pro tapers come with it? if so good score mate, there good bars! great job on gettin ur bike mate, and welcome to miniriders!
