I confirm that 100% to Nestor.10000 km without problems,with a little noise
and occasional maintenance with carbon belt spray.
no oil lubrication.
I have come up with an electrical,motorized spray can solution.
That way I don't even have to dismantle the trunk.
simply,maintenance-free and unproblematic.
Actuate the spray pump for 10 sec. every 1000 km
