Slowly losing coolant from reserve tank

RC · 07-21-2017, 01:26 PM

My reserve coolant has been inching away over the past 2000 miles. I added a little and now its creeped back down again. When doing my valve check today I found the hose clamp that attached to the top of the reserve to be a little loose, so I reattached it and hope that was the source. But I just don't see how it would lose from that. The bike hasn't been on its side at all, and if half full it can't really vibrate or slosh out.

Otherwise I have 2 suspicions- one that maybe I didn't get everything tightened up well after my 2 year coolant change a couple thousand miles ago. But I don't see any leaking. The other is a bit of a stretch, but a combination of high temperatures and high altitude might be taking a toll on the coolant? But the heat range has stayed normal as I refilled the reserve tank when it got low, so all is safe for now.
