Every time I ride, some coolant leaks down the right-hand side of the bike. It seems to be leaking in the vicinity of the radiator cap, but I cannot verify where exactly.

When I serviced the radiator a few months ago, I did notice a lot of crud buildup on the cap seal, but I cleaned it out pretty well. The bike still leaks.

I thought I read something about this problem before, but the website is just too slow for searching right now. Thanks for helping!

 

Yea i have an 04 1000rr and my coolant also leaks a little. let me know if you find info on it.

 

I had a similar issue on my 05. It turned out that the coolant hoses were just not tight. I removed the fairings and checked them all. All of the hose clamps were loose. Im not sure if this on all bikes, but it was on mine.

 

Yup, that was exactly the problem! I found 4 loose worm clamps that I tightened with a phillips. No more leakage.

Thanks for pointing that out, justasquid.
