Coolant smell?

Yetsreday and today I noticed a strong coolant smell when bike is on. I checked and didnt see any areas leaking. Bike stays in garage so I think I would notice a leak on the ground. Coolant level sits in the middle between high and low on the overflow tank. Anyone experienced this before and did it lead to something bad?

I'd check all the hoses first and make sure you don't have a slight leak coming from somewhere. Also, pull the right front cover off the bike and check that your radiator cap is on tightly and that those hoses are snug. Check the coolant hoses going into your cylinders. And then check around the overflow bottle to make sure all hoses are cinched down tightly. If you have an internal leak, you shouldn't smell anything (I don't think), so shoot for the obvious first. Hopefully it's just a slightly loose pipe band.

Cindy is right on with this.
Check the hoses especially the one upper left (facing the bike) and make sure they are snug. If you have gone through some temperature changes lately the hose can develop what is known as a "cold water leak" (different materials expand and contract differently)
What you may be smelling is a fine misting from the hose, just enough to get the whiff of coolant smell.

Also check hoses and the o-rings on the pipes that go into the top of each head.

Check overflow bottle too.

An internal coolant leak shows up by white smoke out the exhaust or a chocolate milk like residue on the oil cap, and if you can smell it, it has to be external.

Most likely the coolant leak, if there is one, is at the lower end of the pipe Dianna's talking about; right side as you sit on the bike, front cylinder. It could also be the hose at the upper end of that same pipe; check the corresponding pipe on the other side of the rear cylinder, too.

I'd bet, if you look closely, when you smell the coolant you'll see some moisture down in the bottom of the valley between the cylinders... Been there before, a couple times or three.

You could also be leaking from the long hose that meets a metal fitting aft of the air box. It it's there, it can drip onto the rear cylinder and you can get the smell. The hose runs aft along the to[ of the air box and then makes a 90 degree turn to the left as you look at it from the rear of the bike about where the rear of the gas tank sits.

Been there too. Had a very slight coolant smell. Finally noticed a small amount of fluid around the rear cylinder pipe. It got fixed when the shop did my stator change. No more coolant smell
