Just joined the YZ450F family with the purchase of a 2011. The bike is awesome and is already tricked out with a number of offroad goodies. I'm coming off a 2010 KX450F with a Rekluse CORE EXP auto clutch. The Yamaha has a Rekluse Manual CORE clutch and I'm thinking about getting the CORE EXP Add-on kit for tight, single track riding. Anyone running the anti-stalling add-on kit? If so, what do you think?
