New to bike maintenance and trying to figure this out. I just got a pair of '87 Yamaha FZ600's. One does not run yet. I believe the previous owner fried the starter relay and goofed up the wires after changing out the original fuse box to add a new plastic fuse boxes. The bike that does run does not go over 85 mph. I need to change out the original oil and add synthetic. I also need to get a new clutch and springs. How good are EBC and Vesrah clutch disks? Has anyone used Amsoil synthetic oil in there bike/s?
