Has anyone tried the Dynatech ignition box? Is there a quick shift module that piggy backs on the Dynatech? What brand? As far as Slipper clutch's-What year YZF450F kits will also fit on a 2008 WR450F? All the vendors of slipper clutch's only have part numbers for the YZF450F application. Obviously the 2010/11 YZF is a different motor-so no go on that part#. Anyone?
