id say dont worry about looks until it runs the way you want it though...... id definately say, if the terrain is rougher, get nerfs (i like dg, but it doesnt matter, they're all good) get some Kenda Klaw tires (they are a lil heavy, but not terrible) i have the FMF powercore II on mine, i love it, soon imma look into a Factory 7 or an LRD... dont wory bout the a-arms yet, Vforce 3reeds, or Boyseen reeds are probably pretty good..cuz the stock ones on it are OEM, and they arent so good... DEFINATELY GET RID OF OIL INJECTION....
i use 14/40 gearing, i suggest it cuz it pulls harder, and gives you more of the full potential of your top end, uhhhm, if i think of anything else ill put it up, but im not thinking right now lol ohhh yeah -- you can get it bored, and get a wiseco piston too!
