Hi Peeps, I am sure this has been asked before, but a quick search didn't list anything. My ES is coming up on 20,000 miles, the engine has been regularly serviced, but the fork oil has never been changed so I figured it was time to do it. I have the Yamaha service manual for this bike, but under the maintenance section it does not list changing fork oil (apparently Yamaha don't consider this a service item!!). Anyway the manual explains how to completely disassemble the forks and put them back together and it states to use 01 fork oil and put 505cm3 in the left fork and 493cm3 in the right leg.
Can anyone tell me what grade 01 oil is? Is it 1W oil or is 01 oil a yamaha oil of a different grade? Also do we really add different amounts to each leg? I just wanted to unscrew the fork outer, drain the oil, add new oil and then screw the outer back on. The manual gives an oil level to be measured, but that requires removing the top of the fork and the springs, which is far more work than I really wanted to do.. Am open to any suggestions, I have been servicing motorcycles for many years and know how to strip forks, just don't want to for just an oil change..
Regards Gary
