[QUOTE="CDA, post: 12829, member: 103"] You might want to think about that one. I rode a custom built KX250 with a 300 kit and a WR tranny and geared for high speeds. It was built by Team Green so it had a lot of motor work done, but I felt you had to shift too much with the WR tranny to get the motor in the sweat spot, even with a heavier flywheel. I would say (and this is just me, so take it as you will) that you should play with gearing first after the 265 kit is done and maybe a flywheel adjustment before going out and installing the WR tranny....But again that is just me..
