Those who ride short distances and don't ride often will likely never see the problem as there is not enough time for it to take effect. Harley oil transfer is isolated to touring models and especially those that are ridden long distances, which really blends the oil, builds pressure, and gives the oil much time to slowly transfer over. In 2017 Harley released the Milwaukee-Eight motor and it didn't take long for the same issue to arise on select bikes. This seemed to fix the issue for those bikes that experienced it. Engineers resigned the main seal and spacer between the transmission and primary for closer tolerances. Harley tried to fix this on the 2014-2016 twin cam models. Clearly this method is not working all the time and there are issues. This pressure is supposed to be relieved through the hollow main transmission shaft and back into the transmission and breath through the same transmission breather tube. The oil here also gets blended and creates pressure when things are turning. The primary case has the clutch, compensator, primary chain and is an oil bath system. A push rod goes all the way through the hollow main shaft and it engages and disengages the clutch basket. The main shaft of the transmission extends all the way over to the primary side (right side). To help with the pressure, Harley designed a breathing transmission which is why you'll see the vent hose on the top of your transmission. When the gears are turning, air and oil get blended and mixed around covering everything, and pressure is created. There are two shafts in the transmission, the main shaft and the countershaft, both having 6 gears. This has been a frustrating issue for Harley over the years because it doesn't happen to all of their motorcycles. This is normal and it's only when larger amounts are transferring that causes issues. Understand, there will always be a small amount of Harley oil transfer between the transmission and primary cases (small amounts-2 oz or so).

This eventually leaves the transmission very low on oil and the primary with too much oil. Harley oil transfer is when oil moves over from the transmission into the primary case.
