here are my sudjestions use a kxf450 dirtbike radiator, extend the swing arm at least +4 for paint I think candy green apple frame. with eather black plastics and shiny chrome a-arms, swing arm, and rims or white plastics and sharp blue triangle/diamond like accents like the yamaha dirtbike graffics but way cooler. and/or have the a-arms and swing arm and rims black pearl flake its like metallic black but with sort of a glitterly look.
and my fav part the exhaust just borrow an ascedaline torch heat up the silencer tube bends and shape it in and arround the frame so it matches up to the rear stock bolts if it looks like there's enough length in the tube to reach it. if not fab and weld a spot for you to bolt it up. as for that kx500 shock fab a new spot to mount it when you cut the swing arm in half to add the bar stock when or if you lengthen it. if ti dosent want to fit in the cradle or if it makes the bik sit to low or to high.
Im looking for ward to seeing pictures I:I
