There is a bunch of different places but ufo plastics is pretty good and I did a kx100 front fender on mine and you can get grapics from skda,rival ink,backyard design or eBay
how much more power do you think the stock 140 vs the bigbore 170 and even cammed, also ever hear of fuel tank bloating? i bought mine 2nd had it was crashed but i cant see any bends as to why the fuel tank doesnt sit fully (front bolt is 1/4in too forward) other than cosmetics it runs first push
