I had them on my banshee and they only looked good. It still overheated as usual. I ended up going custom. Pro circuit is making an upgraded one. It has some different kind of pattern or something. When that comes out I'm sure everyone will run those instead of the cv4 IMO. TRy something different. The hot rod market makes tons of radiator hoses in larger diameters tat can be clamped on and they are clear. I had blue dye in my banshee and it looked sick!! For the kawie you wouldnt need dye cuz the coolant is already green. And the hoses dont help if you dont upgrade the pump. Im not sure but does ne one know if the boyesen is out yet??been considering getting them. do they really have any cooling or performance advantages or do they just look good? anybody use them?
