Does anybody know what the stock weight oil in the trans for a 05 Fat Boy is. My manual just gives me part numbers?
I have an 05 Fat Boy. Does anybody know what the stock trans oil weight is? The manual only gives me a Harley part number and I want to put in M1. Thanks (Mahalo) from Hawaii.
The Harley part number for the stock trans oil is (99892-84 quart or 99891-84 gallon). I want to switch to Mobil 1 syn. Still running the OEM 5 speed trans. The average temp here in Hawaii is around 90 degrees. 75W-140 or 75/90. My ridding style vary from cruzzin to ridding like I stole it.
