I am putting on a Electrex Dakar Dual Sport Kit on my '00 yz and am running into troubles. I am trying to take off the flywheel with a regular pully puller with the arms that reach around the flywheel. Is this okay? I really want to get this new stator and flywheel this weekend on and can't get ahold of a Yamaha flywheel puller. I crank and crank on the sucker but am afraid to do it too tough because it seems like it is going to bend it. Does it just take a crap load of force, or is there something else holding it on besides the crankshaft nut, or is this just the wrong tool for the job? What should I do? Thanks in advance.
