Oil/lube leak.

Ok, put a hundred miles on today (incredible riding weather in SW FL.) Stopped 1/2 way thru for a bladder break and a drink. didnt notice anything unusual, but when I got home, I found this...

looks like its from the final drive, but its full, and clean (checked when I got home). this stuff is dirty, possibly from the road/ect. but its not really a brown or black, its more like aluminum colored..

any help in figuring where it came from?

There's also fluid that goes into that rear "pumpkin"...if the axle seal for that unit is bad, you could get the same....
I suggest draining your rear fluid (gear oil), and see if its black like your stain...if so, remove the rear wheel, and examine the seal....good idea to change your rear fluid anyway if you havent done so...

I pulled the fill plug on the rear end to check the level... I could see in it rather well, and the oil in there is about as clean as the day it came out of the bottle...

would be wondering how excess moly got there.. the entire side of the bike is dry as a bone except there on the wheel.

It couldda worked its way outta the slot by centrifugal force...very little grease is actually needed at that spot....I paint white lithium onto mine...
Take yer wheel off, just wipe doen any excess, and it should go away...better too much then none at all though....when my bike was a rat, I didnt care...now, especially with whitewalls, I kinda gotta, lol...

well, as of right now, the bike is sitting (parked after the trip). in the morning I will see if there is any more drips/leaks. It was exactly 1/2 of the trip when I stopped long enough for anything to leak out.

I have not taken the wheel off yet to check the splines (on my list of things to do) due to lack of time, and/or ambition LOL. Also more than a little concerned about what I will find... if its bad in there, my transportation for work is sidelined until fixed.. with no income from work, no fix... kinda a catch 22.

However, with 27000 miles on it, if there was no lube from the factory, I would have to imagine that the splines are beyond any servicablity. so I am going on the assumption that somewhere/sometime they where lubed up.

The splines to worry about are the ones where the driveshaft meets the tranny...thing to watch by the rear wheel are/is the rubber damper thats in there...the diff to wheel connection rarely goes bad...probably just overgreased, and a long trip will make the rear heat up some, causing the grease to thin...Im sure its nothing to worry about...just clean off the excess inside, and you'll be good to go...

hmm, the front end of the drive shaft then, not the rear end (where it meets the final drive).. just the opposite of what the spline lube write up says.
