QLink Frontrunner where do you change gear oil in rear end

Typically most gear drive motorcycles use the same type of system. There will be a small bolt either 8mm or 10mm or a Phillips head . That will be at the bottom of the gear case just below the rear axle. Remove the bolt and let it drain. There should be a smaller screw or bolt of some sort above the axle. That will be the " weep " hole. Once you finish emptying the gear box. You re install the drain plug and fill the gear box through the weep hole. You fill it til it starts to come out past the threads. That is the correct fluid amount. Re install the weep hole plug and you're good to go.
