Thanks for watching @rodrigoantunes8502. ATF in the primary case has been the norm for as far as I can remember. ATF is designed to provide lubrication for gears/chains and proper operation of wet clutches. Synthetic ATF resists heat better and lasts longer between changes. It also helps with less clutch drag/slip and less clatter when shifting. It will not damage clutch plates. Thick grade oils are too sticky not best for streamline lubrication and tend to foam up.
I hate ATF and don't understand why anyone would use it, plus it can leak in thru the left side main bearing. Especially on the older models that don't use a seal there. Good ol Penngrade Straight 40W for me. Who cares if it foams up? There's only a small amount in there to keep the chain wet and to whisk over the clutch plates to keep them cool.
It used to be said about British bikes, if there isn’t oil on the floor underneath your bike there probably isn’t any oil in it 👍
Haha perfectly said!
ATF in the primary chain?? Doesnt damage the disc plates??? ATF will clean all the sludge lefted from other oils...
