"Everybody has a plan, until they get hit in the face" - Mike Tyson

Well, I'm pretty good at beating myself up.
The plan was to work on my 2015 650 in the house this winter while I healed up from rt. hip and lt. knee replacements.
I've never done a valve lash check with a shim under bucket engine before. So, I did what any backyard mechanic would do. I watched a bunch of you tubers and jumped right in.
So we get what we have here.
If any one could draw a diagram of what position the rear two camshafts should be in when the front cylinder is in TDC on the compression stroke, that would be great.
Now an ignorant question....
How do you know if the cylinder is in compression stroke?
I have Haynes manual now. I didn't when I started

.
Poor thing...

I have everything just like this picture. I just don't know how the rear cylinder lobes are supposed be.

I appreciate the replies and the pictures.

My main problem is I had a brain fart. I turned the engine with the forward exhaust cam out.
The intake cam jumped a couple of teeth (at least). I'm sure I can figure it out with the info I've been given.
Thanks every body!
