hi guys,
I have just pulled the head off my parent TR magna to change a burnt valve. When I went to put the head back on, I found I couldn't fit the cam gear back on as the chain had tensioned itself somehow. My question is, that I know the TR has a ratchet system on the tensioner, how do I release the ratchet to allow the tensioner to go back. I already have the sump off.
TIA
Michael
