Im not adverse to having parts look nice and function well, but there comes a point when its not worth it. Bonvo already pointed out he swapped in a radiator for something like $50. If you dont want the poor looking (purely opinion) swap then you can pick up the $300 Koyorad. Theres a pretty big difference in price. The third thing is that Chinese knock-of on CL will probably be something like $200-$225. Its great that its a shiny aluminum radiator and $100 less than that Koyorad, but who knows what kind of quality youre going to get. Poor cooling, busted welds, irregular fitment. When the cons outweigh the $50 junkyard swap youre now wasting the price difference of $175 instead of saving $100.
Swap in a nice junkyard radiator and use your savings to purchase new spark plugs, cap, and other misc. tune-up parts to help your ride run better. You will be far happier.
