Mineral Oil - Used in primary
Used in primary, on softail intial testing no clatter/noise Was a hot day (26c) and primary was hot (after 2h:30m non stop riding) but not excessive , clutch didn't drag and disengaged freely cold and hot. . Intend on doing more regular changes than recommended service minimum so happy to use mineral oil in primary. Will be using different Fully synthetic in transmission to reduce the 'Harley clunk'..(Hopefully)..
