ok. I hit a branch yesterday and it speared my rad and put a hole in it!!!! I pretty much ruined my may long riding weekend and I was/am PISSED!!!!! so now I need to buy new rads. I was looking on ebay and there is ones made in china for 120$ per set!!! not bad compared to 400$ for new OEM ones. here is a link to the ebay chinese ones: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=260780692382&viewitem=&sspagename=STRK%3AMEWAX%3AIT they say they offer 30% more flow, is that true? and what does 2 row 40mm core mean? are these rads bigger than stock? I was going to get devol rad guards so broken rads dont ruin any more weekened, but I am worried that the rad guards wont fit properly on the chinese rads? ps: bike is a 2005 crf 450r thanks.
