For a GL500...It depends on the bike you begin with. For a GL500, it's a bolt-on affair. For all CX500s except the 1982, you will need to also replace the entire wiring harness, handlebar controls, and ignition coils. The CX500s run CDI ignition, and the 650s and GLs run transistor ignition. So you'll have to swap that over if you want to run a 650 motor. The front engine hanger needs to be extensively modified. For the GL bikes, you can swap the GL650 engine hanger over. For the CX, you have to cut, modify, and weld the front engine hanger. The heads are taller, so the studs that the hanger bolts to are further out. If you're using a 500 radiator and a custom fan like I did, that's all you need to do. If you're using the 650 radiator you'll also need to cut out the cross brace from the engine hanger, and weld in a piece of metal tubing to brace it. This is so the hose has clearance. (CX500 radiator has intake on the side, 650 has intake in the center). See the other posts in this series for more pictures. Also, depending on the source of the 650 motor, you may need to swap the output shaft, otherwise it will not mate to a CX500 driveshaft. 500 carbs will need to be rejetted for a CX, whereas for a GL you can swap over the GL650 carbs without problems.
