Soooooo....
I did my own valve adjustment and it sucked but almost went well.
On the test ride I found out that the rear cyl spark plug rubber gasket is missing. Found it on my garage floor.
The bike is squirting oil out of there.
How do I get this gasket back in without rotating the engine again? I can lift the cover a little bit. Is it possible to remove if I take the rear shock bolt out?
Also thinking of trying to squeeze gasket maker goop and hope for the best. Gluing in a rubber sheet along the wall around the gap between the cover and the head?

Watcha think?

Thanks!

When I did my first valve adjustment, I found my rear cylinder like that. I think you can remove that rear valve cover, you just have to move stuff out of the way.

If I remember correctly there is a big groove where the rubber grommet goes, so you'd have to use a lot of silicone in there. I personally wouldn't go that route.

My recommendation is to fix it properly.
Oil leaks are not something you want to be skimping on with a two wheeled vehicle.

take the cover back off, remove the gaskets
clean them and the cover ditches ( with break cleaner )

allow this to dry

place the gaskets in the groove

lift a small area of the gasket

use small dots of super glue about 15 mm apart to secure the gaskets in the cover
place the glue on the gasket and place it in the groove at once. Press and hold it a few seconds then advance be careful not to stretch the "rubber" gaskets.

Its nice to know that the gaskets will not wander off while assembling

I did this to my bike when I did the rotation
a couple of months ago, this works well.

No leaks so far.

be careful with the super glue...

YMMV

Too late to double check your work twice! LOL!

I found it damn near impossible to remove the rear cover without rotating the motor down.

If I were you, I would:

Kick my own a$$ for not checking this important part of re-assembly.

Then, I would rotate the engine and do it right. I would also take advantage of it by having the muffler Ceramic Coated Satin Black, since it's now going on winter and you're going to remove it anyway. That way, the effort won't seem like an entire waste.

It's a tough break, but I agree with those advising you to tear it back down and do the job right. It doesn't take much oil on your rear tire to cause a wreck....

Gentlemen I've come to report great success.
I was able to lift the cover just enough to slide the gasket into the gap and place it in the groove with my fingers/dental tools.

Thanks all!
