Thanks in advance for any info. Just purchased low hours '04 WR450 and has slow drip of oil falling from bottom-inner radiator. It shows a creep within the fins, but also shows on frame. Could it be blowing from pressure release exit? I'm not sure, but assume that is the hole directly where the oil may be blowing. Also, the handlebars were replaced recently. Could the pressure relief be engaged? Thanks for your time!
