FJ1100 Leaking Gas/Oil Mix when sitting for a day or more.

My 1984 FJ1100 does not want to keep fluid inside of it. If I run it for a while, the next day when I go out to check on it, there will be a small puddle of gas/oil mixture pooling around the kickstand. Any Ideas? Does that round plate that says Yamaha come off and would there be something I could replace in there? It looks like that may be where it is leaking from but I am not sure. PLEASE HELP ME!!! If I bought carb kits from Randy, does anyone know what I should expect to pay to have them put in? Would you recommend trying it myself? I have done a few manifold gaskets in cars as well as other things. Would it be too hard to try myself? Is there any help out there for the steps I need to take to get them installed? Thanks, Jenos713.

Is it a gas/oil mixture or hydraulic fluid?
When the seals in the clutch slave cylinder start to leak it tends to drip out onto the frame and down the kickstand, if parked that way.
That's what i'd check first. Stick your finger in it and have a whiff, then let us know.

I just guessed it was oil fuel mix. Did not dissipate like gas, but rather stays there like oil. It does not smell like fuel either. Is there a way to check the slave cyl?

look in the sight window of the clutch master and see if there is fluid showing.... is the bike hard to put in gear?

there are only three bolts holding the clutch slave in place.... easy enough to pull it off and see if its wet on the backside.


KOokaloo!

and don't start the engine while you have it unbolted.

Oh c'mon randy, everyone needs to shoot their pushrod under their workbench at least once!!

It also could be an overlubed chain just dripping off.

Oil filter housing drain screw drips near the side stand if the threads are buggered.
