Thank you Antwon.
I'll do some checking, but Tusk rad, as well as Mylers one, look suspiciously just like "cheapy" Chinese ones available from multiple sources. When I blow up the pics, I can see the same welds (much rougher then OEM), and same construction. On unpainted rads this is pretty obvious, not so much on painted ones (paint obscures the imperfections in welds.... somewhat).
As far as painting,.......my experience with radiators that I replaced in the past (mostly on Jeeps), is that they come pretty greasy (unpainted ones) due to the manufacturing process. In order to paint them, one has to degrease them first, in a "bath" with several chemicals, in several stages. Even then, paint starts to peel from the fins rather quickly, and shortly after, from the tanks as well. I would not paint it, for it'll look like crap pretty quick.
As far as manufacturing these rads goes,.........I never mentioned before, but I owned two car dealerships in the past. From what I know about new car manufacturing (and I am pretty sure it's the same for the motorcycles), factories (in this case KHI) source out ALMOST everything to outside suppliers in Malaysia, Singapore, China, Thailand, Mexico, etc. (labor costs). Once these suppliers are tooled up for production of some component, they keep producing even after the ordering manufacturer stops ordering (model discontinuation, and other reasons,.....like KHI getting a LOT of warranty claims, because of the substandard component). After the orders stop, these components are found on "aftermarket" sites, much cheaper than the "OEM" labeled ones, although they are essentially the same product (in SOME cases minus factory QC!). I owned three European franchises, one Japanese, and one American (under two roofs), and they were all the same. In case of VW (one of my Euro franchises), my service department was able to install some component either as "OEM" (with appropriate VW markings), or "aftermarket" (same component, from the same supplier, minus VW markings) as a MUCH cheaper alternative for the customer. And that was while the model of the vehicle/component was still available from the "mother factory" in Wolfsburg.
It would be interesting to find out where are the rads sold by Tusk/Mylers/ and other "aftermarket" suppliers actually made, but I am sure they (aftermarket houses) don't make them by themselves. That's why I was asking if anyone knows WHERE are the OEM rads for KHI actually made. As I also know, manufacturers of the components change even during the "life" of the vehicle model. After model discontinuation, some smaller manufacturers (of radiators, water pumps, alternators, etc.), buy prints/tooling from the original supplier for OEM, and they start cranking out "aftermarket" components, cheaper! "Cheaper" is possible because they can start "cutting corners" (example,....offering unpainted radiators), for they don't have to meet the strict factory QC.
Sorry about writing a novel here.
