you can have these for $80 incl postage..spun polished aluminum..they sit just inside the throttle by about 2mm..there about 75mm tall..and flare to 75mm across the top..you just need to get some one who welds aluminium to weld some little tabs on the sides to fix them in place..piece of cake i'm not needing them anymore as i wanna run an airbox..although they look soooo sexy! i had them made buy a guy at Brisbane metal spinning..
