After dragging my feet I'm finally getting to reassembling the timing chest on my MK II.

When I initially assembled the engine I employed this to hold the rotation of the crankshaft.

Torqueing the Camshaft Nut on an Otherwise Assembled Engine


I had to open up the timing chest to diagnose and repair an oil pressure issue . I found it necessary to remove the intermediate shaft and timing chain/sprockets to perform some needed work. Now I have to torque the camshaft sprocket. What is the best way to lock the engine rotation to facilitate torqueing the camshaft nut?

Also I have 9 links (10 pins) between my timing chain sprocket marks. This seems to be correct but I can't find anything specific in my brief searches.
 
ten rollers apart.
watch the torque values on the camshaft nut and don't use an impact drive. You will find the values in the shop manual at the front under technical data. I add a spot of loctite 243.
 
to lock the flywheel I use a 17mm bar just like you have in your picture but protect the surface area with two small blocks of hardwood across the top of the mating surface.

Ahh, the engine is assembled other than the timing chest.

Oh boy???? you will apply strain to the chain and the intermediate shaft when you torque up the nuts. You have an cutaway timing cover??? or best get the Andover Norton tool for the job or you will bugger up that shaft where it fits into the right hand engine case. You may need to wait until its in your bike and hold it from turning at the drive side sprocket.

+1 on the Andover Tool. IMHO, easier, faster, and better than a cutaway timing cover and absolutely needed to tighten/loosen that nut in all cases.
 
It looks like you have two cylinder base gaskets. One works great, two are too squashy and try to ooze out while tightening the cylinder base nuts.

Look closely it's not 2 cylinder base gaskets.
Besides that picture was taken over a year ago before the top end was installed.
