Is it necessary to change the gear case oils?
I agree with 450RMAN. The gears and bearings will last a lot longer if you change it. The maintenance schedule says to change it every 2 years, but if you ride in a lot of mud and water, I would change it more often. I would check it every time I rode in mud and water and if I saw any water in it, I would change it immediately.Is it necessary to change the gear case oils?
