hi. why does the oil from the gearbox flow into the primaries? It doesn't leak or drip from the motorcycle anywhere.

I have never heard of tranny oil migration in an EVO engine bike
When it happens on M8`s it`s due to trans oil traveling along the clutch throw out rod
Are you SURE it`s trans fluid ?
More common would be engine oil coming past the crankshaft seal
Provide more details please

Oil doesn`t flow from a 5-speed gearbox to the primary, unless you store the bike laying down on its left side.

Yes, but it does not lay on its side...
You need to set all the oils to the correct level and check them all after a few hundred miles to determine what the issue is.

Are you checking this via the transmission dipstick? Please provide photo of it.

I'm checking the transmission probe. It's decreasing all the time. and in the primary, the oil increases. maybe the probe is wrong?
