Antifreeze leak

Post by Deerskinlake »



200


7GL 1800 with 12,000 original miles. Noticed a small puddle of antifreeze leaking under the bike , near middle of engine. Took off right side cover after drying everything off and noticed a pooling of antifreeze alongside the engine in the webbing of the casting. All hoses in the area looked just fine. Removed right faring pocket and overflow hose was fine nothing wet up there. Started up the bike warmed it up fully and watched behind the Side cover and no leak appeared. What could have caused this? Thanks to all.

There is a O ring right there in that area. The silver pipe going into the Cyl head.
Go to Bike bandit and look your bike up its part I believe its part #23.
But thats just my 2 cent best guess.

I have a 2009, which I purchased brand new in the crate in October 2010, and the first winter it went through, it dumped about a thimble full of antifreeze on the floor without being run at all during the winter, and being stored in the cold. Never did it again. Just my experience, and probably not yours. Might be just from sitting too much and not having the heck ridden out of it. It had been in a crate for over a year, and I had ridden it a thousand miles before putting it up for that first winter.
It ain't about the destination - it's all about the journey

Assuming my path on your picture is about right, to correct you leak(s), it will require that the fuel tank be removed.

Thanks much for the reply.... I was afraid that was going to be the case I've heard this from some other people also.

I'll add a question to this thread:

Do people tend to change their hoses at a certain point or do they just leave them until there's a leak? I have a 2007 Wing and it's been on my mind.

I have an 07 and from what I have read is that hoses don't normally need changed unless there is a problem. The OP could have a leaking hose from a hose clamp or from dry rot from sitting alot. And as Greg said its likely under the tank.

More often than not, the leaks are not from the hoses themselves, but from where the hose is clamped to the engine/radiator, etc. Tightening the clamp will usually fix it.

On an 07, they will be fine. I changed the ones out on my 88 because a few of them were getting hard. I did it more as preventive maintenance on 30+ year old rubber.
