i recently bought a used 2006 Yamaha YZ250F. it is in great condition and runs awesome. but the people who had it before me sold it becuase his wife couldnt start it. they used it for trail riding. so he had the suspension set softer than normal. so last night i set the suspension back to the factory settings. will that be stiff enough to take it to the local track? or should i make it stiffer than the book says?thanks. 2006 Yamaha YZ 250F
