I´m looking everywhere trying to find out the oil capacity of the V-Max middle gear case. I can´t find the information in the oem service manual but the final drive, Differential is listed. My local dealer´s service manager told me that there was no such thing as a middle gear even though it´s listed in the parts manuals. I told him he shouldn´t be a service manager because he doesn´t know his product and asked him how long he´s been working on Yamahas. A little help would be appreciated.
