The oil seal (#2) is press fit into the side cover....the circlip (#8) and washer (#7) goes inside the case against the engine block.

It's easiest to remove the side cover and use a pick to get the old oil seal out, clean the landing, and evenly press fit in the new seal.

Easy job.  Don't over torque those case bolts. Easy does it 10 n.m. or 7.2 ft.lb (86 in/lbs)

My 85 FJ1100 has a minor oil leak that is coming from the shift shaft as far as I can tell.  The parts diagram shows a seal (#2 in the diagram).  I'm confused where this seal is located.  To replace this seal, do I have to remove the crankcase cover to get to it.  When I look under the bike, behind the crankcase cover, I can see the circlip on the shift shaft (see picture below).  The diagram shows the oil seal on the outside of this circlip.  If that's the case, where is this seal?  And there is no seal on the engine side of the circlip according to the diagram.  So what's keeping the oil from leaking past the circlip???

I feel like this is a stupid question but I'm confused. 

Thanks to the EPA the Canadian and US market FJ's run lean from the factory.....not so in other region's..

Any changes to the efficiency of the exhaust system, intake filtration or advance on the timing, will make these lean factory settings worse. Your bike will run warmer than normal.

I suggest removing the stock #37.5 pilots and installing #40.0 or #42.5 pilots, removing the stock  #110 mains and installing #115 or #117.5 mains and adding a 1/2 step washer shim under your needles.

Your engine will thank you.

Do a hot compression check with open throttle.
 Disconnect the vacuum advance (plug port at manifold) pop in some fresh plugs, go for a ride and get a color reading on the plugs. Maybe it's just one carb acting up?
It's possible your brass needle jets (aka emulsion tubes) are worn.
It's possible your float needle seats or needle seat O rings are slightly leaking causing your fuel bowl levels to be high. When you bike is off there are no signs of leaking on the floor because your fuel pump is holding back the flow (as it should)

RPM Robert can chime in here with his experience...

Cheers lad

My condolences.

The guys behind me tell me my bike is running rich as I am leaving them in the dust.
First I will check the air filter, I know it's good, but that's always a thing.
I'm not real worries about it, but it's going to be looked at sometime soon.
Buy a new set of carbs or would the emulsion tubes be worn out?
Wallered out, oval, you know the issue, I'm sure.
If so, would I also need to replace the adjustable needles?
Talking out loud, looking for input.

There are some incredible roads in the Springfield area, east and south, you'll love it.

My heart and prayers go out to you and your family, friends.
My thanks for all he did, and for all you continue to do.

Looking for the right-side or both-side covers in black midnight blue color.
If anyone has them, please let me know.

How much?
