A couple of weeks ago I noticed a small puddle under my K75.
The puddle was about the size of my fist.
It looked like oil. It felt like oil.
The mysterious part was the location of this puddle.
It was under my left hard case.
I wiped it up with a shop towel. I looked directly above the puddle and wondered why my hard case was leaking oil.
Sure enough the underside of the bag was coated in oil.
I wiped the the oil off the bag.
I looked forward of the bag, thinking maybe it was being sprayed from the front.
All was clean.
I opened the bag.
All was dry.
I threw the oily rag away, and not feeling like dealing with a problem, I decided to forgot about the whole thing.
I subsequently saw the puddle a few days later. I continued watchful waiting and ignored it some more.
More ignoring this weekend as I took the GT for a ride.
Yesterday, I decide to pull the bikes out of the garage to wash them.
By now I've completely forgotten about the oil leak.
As I pull the left bag off the K75, I put my hand underneath to pull it off. It is coated in oil.
Hmmm, seems it's time to trouble shoot the case of the mysterious oil leak.
The back of the bag is coated with oil.
The rail that holds the bag is coated with oil.
Did I mention that this is clean oil?
Hmmmm, the oil is coming from above.
Like maybe....the tail fin
Where a spare quart of oil has been tossing around for the last year?
I open the tail fin...things are very...moist.
The cover of spare quart, which had been opened at some time, came loose, and filled the tail fin, and found some hole to slowly drain out.
I pulled everything out. Cleaned what I could, threw out the rest.
Put the spare quart into a zip lock bag
And finished cleaning the bike.
Another mechanical mystery solved.
