What type of fork oil and how much fork oil should I use in my CB360 / CL360 / CJ360?

Factory spec on the fork oil is 135 - 140cc (4.6 - 4.7 ozs.) of premium quality ATF (automatic transmission fluid), however we recommend a 10W (light rider) to 15W (heavy rider) motorcycle fork oil. ATF is approximately 5W and replacing it with a heavier weight oil will stiffen up your front end.
