Good morning my m109r family ended up doing my own work on my motorcycle since all the repair shops I called are busy for a couple months. I had a tapping sound coming from the rear upper cylinder head, upon getting to the problem the picture is what I discovered. My question is do I have to open my clutch case to release pressure off the valves or can I remove the camshaft journal holder without removing the clutch case. Thank you to all in advance!!!!
