Ran the bike for a few minutes tonight, after changing the oil & draining old gas.

While it was running I didn't notice anything underneath it, but after I turned it off and it sat for a couple minutes, a quarter-sized spot of antifreeze appeared on the garage floor.

Checked underneath, and noticed a spot of antifreeze (shown in picture).

This is right near the gear shifter, on the backside of the casing.

Didn't notice it anywhere else, and can't quite figure out yet where it may have come from.

FYI - it's no where near the overflow tube.

There's a lot of crud and junk around there on the underside, but nothing that resembles antifreeze. Only grease/oil.



Also - After moving the bike and letting it sit for the rest of the evening, no more antifreeze has appeared or dripped on the floor.



Any thoughts anyone. Besides an unfortunate antifreeze leak from the engine casing...

It probably came from the weep hole. It isn't unknown for a bike that has sat up for an extended period of time to weep for a while and fix itself.

Well I was wondering about that Weep hole also. Where is it??

 

[Blindstitch]

It's in the last place you would look.

 

[Blindstitch]

Look at the red straw.

Look at the red straw.

AHHH. Thanks. That might just be what it's from then. Which would be a relief... literally.

I'll have to keep an eye on it to see.

One way you can check is to stuff a small rag or even a paper towel in there and go for a short ride or just let it run a little bit and see if you get a green spot.

And if the Mechanical seal should go,

Ok, now this morning there's a small quarter-sized spot of antifreeze on the floor where I moved it.

IF it was the weep hole, how much is expected to come out of there? And when?

Even after the bike was shut off for a while?

Although, it isn't much, so I'm wondering if its just the remaining residue dripping down from last night.



Almost done witht the brake rebuild and then I'll take it for a ride to see also.

You will not be able to tell if you have a problem with the Water pump Mechanical seal until you have given the bike a good ride say at least 30/40 miles and some decent sustained speeds.

As Shep said. Monitor your coolant level and watch your temp. gauge. Might even be a good idea to carry a litre of coolant just in case.

Fortunately or unfortunately whichever way you want to look at it the cooling system on these bikes the Overflow bottle bears no resemblance to what's occurring in the cooling system so should never be used to judge how much coolant is in the system.I and several others will back me up on this.Neither of my Coolant overflow bottles have been used in over 6 years of riding these bikes.

Although the manuals state the these are a sealed cooling system they are not the same as a sealed cooling system in modern cars.The pressure in the cooling system never gets high enough to open the Rad cap valve which is a testament to how efficient the cooling system is.If it did you would not need the overflow bottle to tell you there was a problem

True coolant level can only be checked with the Rad cap off.
