I've had this pesky coolant leak I cant track down. I've made sure all the hose clamps are good and tight. I even had the bike running and took a flashlight to look if there are any leaks from the hose/hose clamp connections and nothin, not a drip. Theres a small drip when I ride (coolant spray all over the engine), then when I stop and turn it off, it starts to drip, and I end up with a puddle about 6-8 inches in diameter on the left side. Any suggestions on what else to look for?

I feel your pain, I was experiencing the same problem and I surmised that the spray was probably coming as the cooling fans come on it is blowing the dripping coolant all over the engine. I know you have tightened the clamps but did you use a torque wrench and tighten them to 27-35 inch lbs? I did not resolve my leaking coolant until I tightened them to spec with a torque wrench. Before using the torque wrench I was afraid of making it too tight but I was surprised how loose they were after torquing them to spec. I know how irritating this problem is, I hope this helps. If not, I remember another thread where someone had a problem of the upper radiator tube below the airbox had worn through. You might check that too. Good luck.

is there coolant around your overflow bottles filler cap or under the bottle?? i had coolant running down my right down tube and tightened everthing down many times and still had a leak....i finally used a little silicone sealer around the mouth of the filler neck and no more leak....it would leak around the cap when hitting large bump and leaning hard into corners...it's worth a look....

I had to replace both coolant pipes they were worn thru by rubbing against
each other were they drop down to the radiator.
I have a thread on this about two weeks ago.
I just finished my bike up today, man what a pain!!!
