I've got a shop sink, so I just fill it full of water, tape up the inlets/outlets a hold it under while holding an airgun in the crossover tube nipple. Bubbles. You can do the same thing with soapy water and a spray bottle if you don't have a big enough sink.
Thanks RDTCU. Timberline, yes I'm also glad that it's just the radiator I called the dealership yesterday and still waiting for them to come back with a price quotation. They're usually a bit slow when it comes to parts purchase, cause their main office which handles parts and bikes import, is located in Bali. So the guy here has to contact Bali for information...and that's why in two occasions when I need parts, I bought parts from Hall's Cycle and Italhusky instead. RDTCU, if I understand it correctly, I will have to purchase both the left hand side and right hand side radiator, right? I will search the thread that you mentioned above.
I googled GPI radiator TE 250 and among others I get this, it's from Ali Express: http://www.aliexpress.com/item/RADI..._2&btsid=93f8640f-f3c4-4363-ab25-fd5270012bc8 Is this the one?
No, that's not them, the bottom nipples are wrong. I got mine from Ebay. These are similar to what I got, ignore the picture, it's just a stock photo. http://www.ebay.com/itm/251851389910?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT You may be able to get them to send an actual photo for comparison, I probably would before sending $200+ to china. You don't have to buy both radiators if you're going with factory replacements, but the GPI radiators do come as a set.
Thanks RDTCU. The dealer can order it for me, but it will take about 2 months. Hall's can also get one for me, in the mean time I'm going to try to find a radiator repair shop here and see if they can find the leak and fix it. I checked again, the past few days there was no more coolant puddle under the bike. Maybe the puddle was a result of an over fill when I filled the radiator.
Keep checking your level if you take it out. It's probably only leaking when it's hot and pressurized. Those little pinholes are hard to find when it's cold.

Thanks kuzmich. I read Cyrillic but I don't speak Russian But I google translated it . After several more days watching/looking for leak, and couldn't find it, I decided to just buy a radiator cap and see if it stop the coolant loss. I ordered it from Hall's yesterday along with a left front turn signal. I also ordered the turn signal to save shipping cost...it's $40 for shipping, so if I only purchase the radiator cap, the shipping cost will be too high. Buy two items, and the shipping cost is...still expensive... but a little better. I'll update you all when I receive the cap.
