With cam chain stretch it is hard if not impossible to maintain the correct pin count and cam positions. I would double check the pin count then rotate the motor over a few times by hand (stop if something does not feel right!!) then button it up and ride it!

Always clean things like that before you expose the internal parts.

Maybe I'm missing something here....
You have the valve cover off w/top idler in place and have found your off in alignments right.
And your using OEM non adjustable sprockets...
So why are you taking a chance versus dialing her in at TDC? I don't get it!
Loosen the top idler, using the ignition bolt 17mm bolt, rotate to # 1 TDC. The reposition the the exhaust cam where dimple is perfectly aligned with the head decking.
Then count one pin up and the correct number over (ex KZ900 28 pins) and get your intake on the money....
Seriously, dial her in, why take a chance or where it just won;t run right especially after all you've accomplished now go half ass in your adjustments!

It does rotate freely, so no worries there. The dirt probably looks worse since I upped the contrast wayyy up in the pics so the arrows would be visible. Its still dirty though, duly noted.
Adjustable sprockets would be awesome, but this was a $400 "bucket of bike" special. I'm sewing her up and see if she works.
Thanks for the advice all, much obliged.

I don't know how the liter bikes work, or if some folks replace cam chains with their oil changes, but for a bike with 20 or 30k on it it becomes very hard to make it all line up perfectly.
Button it up and run the nuts off of it!

Look EVERYONE wants EVERYTHING to set up perfect.
Oh well...
Set your crank up ,
Set your EX. cam ,
Count the pins ,
Install IN. cam ,
Button everything up ,
Either oil up or spray some lube on your valve gear ,
Turn the engine over several times with a wrench SLOWLY ,
If nothing is binding ,
and you did the pin count right ,
I would guess you are good to go .
Don't forget to readjust your tensioner after the bike has warmed up .

Funny thing is, I would've sewn her right up and kicked her over except I had to check valve clearances. 5 out of 8 isn't bad, right?
I kid.
Had a couple .04, .05 and .06 readings. The .04 is pretty tight. Might just have to wait until new shims arrive, I'm thinking. I haven't read anything on here to suggest that such tight readings are alright. Right?
