never seen that before. on the vf3 ive seen, the dividers were very thin, except the main horizontal one but it was supporting other dividers so its probly best left alone. without knowing how brittle that plastic is i would be real nervous about grinding on them. besides theyre already pretty thin, i dont see anything to be gained by making them paper thin. im wondering if he just did alittle work on the insert piece and matched it real well to the intake boot and your dividers failed for another reason ? even in a "best case scenario" i dont think theres much to be gained in the reed cage so i cant imagine he would compromise your engine for half a horse power
now grinding some of the honda cages is a different matter. some of them you can gain nearly a whole reed petal worth of extra surface area by removing the dividers but obviously youll then need some special made reeds to account for the missing dividers
