Just popped in a cylinder head.

Flywheel turns backwards <---- backwards ? I though it was only supposed to turn forward.

My re-install process "in order" - best as I can remember :

1.) installed 2 hollow metal guides on two of the four stud bolts that the cylinder head slides onto.
2.) put on head gasket.
3.) put on the cylinder head. bolted snugly the 2 side bolts.
4.) put on 2 hollows metal guides that cam holder goes on.
5.) Installed camshaft and made sure marks (holes) were lined up & down.
6.) Installed rocker assymbly.
7.) set valve lash .004 in and .oo5 out.
8.) installed cam chain tensioner.

Stoped at this point because I was re-turning the flywheel to re-check that valve lash was correct and noticed
that the fly wheel turned backwards (due to back pressure ?) about 1/2". I turned gently backwards and it move 3/4 - 1".

What could it be now ?

That is fine Bro the compression is moving it back on you not a problem. To time it and not have that occur take the plug out. I first thought you meant you started it and the motor was running backwards(HAHA).

Thank you alleyoop!!! I was also not quite sure what gy6fandan was getting at and the possibility of something in the cylinder under the head kept me from writing something like " go ahead and fire it up ",,, LOL!!!

I was going to ask if it was just running backwards . John

CAMSHAFT STOPPER - ((( thanks to "Alleyoop" ))) - new subject researched & disscused in this reply.

So, thank you Alleyoop.

Because of "Alleyoops" warning in a copy of this thread on another forum, I googled the camshaft stopper
and found a discusion in an old "scootdawg" forums dated May 07, 2008.

The direct link and title is :

OEM Valve Adjustment : scootdawg.proboards.com/thread/8313?80264=undefined

It is suggested / stated in the above post that ;
"This stopper is not on any of the high performance cams with the exception of the c6 cam".

I haven't researched / verified this concerning any changes in performance camshafts since that
thread dated in 2008 (six years since then).

It seems to me that if it (camshaft stopper) was installed on stock camshafts - and - that everyone states not to turn the
flywheel counter clockwise during valve adjustment or in any other circumstances that the camshaft stopper
surely plays an important role.

I will have to remove my new "A9" cam and look for variance btween my the A9 camshatf my stock camshaft.

I could not find a "rebuild" or "maintenance" thread / video on rocker arm assymbly. - Just saying it may good
for future reference purposses / general maintenence / troubleshooting.
