Hello,
Just thought I'd share some notes on the install of a manual cam chain tensioner for a cbr/hurricane 600 1987-1990.
In order to get to the cam chain tensioner bolts you will need to remove the tank, airbox, and carbs. You will also need to remove the coolant hose that runs right beside the tensioner. There is simply no other way around this. I tired using every extension and tool known to man and that coolant hose prevents one of the bolts from coming out of the tensioner.
Just thought I'd share and maybe save some time/headache for the next person.
