I`m trying to fix the deflection on my 650,it`s at 1 3/8" and I'd like to get it as tight as possible.I got the rear pulley loose but I can't get the belt off to remove the pulley.Also which is the best way to remove the shim(any homemade jobs that work?)In the manual they say to use a bolt type puller, what is this tool,is it just a bolt that screws in?If so, has anyone made one?THANKS.
