Leaky heads? Yikes!

Post by Sig45227 »

Bike has been sitting for about the last two and a half weeks. It got extremely cold over this last week. so I decided to pull the battery and move it into the corner. When I got the bike on its side stand I immediately saw a few drips of coolant on the left side. It stopped after it made a 3-in diameter puddle. I could see a drip hanging off the cylinder head underneath.

Wondering if it's actually leaking from the head or traveling across and finding its way to a low point. I noticed this when the bike had been sitting for several years after I parked it previously. Mind you I put about 2,500 miles on it this summer with no real issues. It does start hard occasionally but I have never noticed any leaking the entire time. I tried to crank it over and it seemed like it was locked. I am wondering if coolant found its way into the combustion chamber. I guess it's time to yank a plug and look in there. Not what I had planned for the winter or next spring that's for sure.

It's pretty common for the water pump seals to leak a few drops of coolant when it gets really cold out. Check to see if that's where it's coming from, and migrating across.

My 1100 did this every year, even after I replaced the water pump and seals. As soon as spring came around and it warmed up, the leak would magically fix itself.

I've seen coolant tube o-rings do this before, too. ....And magically fix themselves.

If you remove the carbs for anything, go on ahead and replace the orings on coolant tubes. After all the years they get hard. Then when cold they will seep abit.

If not leaking that bad just put a catch pan underneath then make sure radiator and tank are full before a start.
