Hey Benjamin, I was going to do the same thing with my cl175. It,s getting harder to find a good deal on a 2stroke motor, the shifter kart craze has sent the prices through the roof. There are still deals to be had if you look hard enough though. There are a couple of companies that make Baja lighting kits for the popular models like cr's. Cant remember the names right now but wont be hard to find. Wont be a difficult swap, just fabbing up the new motor mounts and making shure your chain line clears the swingarm and the sprockets line up. On some years of some cr motors the drive output is on differant sides of the motor, something to keep in mind. Good luck and keep us posted!!
