It is indeed made by JamesGasket
I bought the Gasket because I open the Primary cover on my Harley XL1200C SPORTSTER 1200 with MissionMaintenance.
I was not sure about OEM, but I chose JamesGasket because of its high reliability.
As expected from JamesGasket, the fitting was perfect and there were no oil leaks.
It works well and the price is right.
