you could buy a complete close ratio transmission with both shafts for the z1r motor from Kawasaki. 13254-001, was the part number on the box. All it said in the price book was "mission assy". Yoshimura sold that same trans for over 600 dollars, but it came in a Kawasaki box with that part number on it!!! Plus all the dogs were undercut from the factory. GREAT road race trans!!!
