Well spotted David, I missed that one. I suppose that this means then that any Tensioner Rattle heard on a Cam Head is more likely to be coming from the Right cylinder area which has the Hydraulic pressure type of tensioner ?.

These pics clearly show the Right Side (underneath the cylinder location) to be the Spring type and the Left Side (top of cylinder location) to be the Hyd. Type.
All of which is going against the present understanding of just what we actually have. Sorry if this only goes to ad further confusion as it does look the opposite to the Haynes set-up.

Incidently, note how the chap in the pictures changed his Tensioners just after a River crossing with Muddy water and Grit all over the engine !!.

Those fotos shows a GS.. NOT a ST.!
They are different. On the RT 2010-2013 it is impossible to get out the left tensioner because of the telelever joint!
