Hello All,
My name is Shawn. I am new to the family! I have to say I really enjoy the site and all the good shared information and suggestions. I am new the H.D world as this is my first Harley. I have had several other bikes however, I am wondering why I never looked at purchasing one until now.... What a great ride!
So my question is.... can I use any off the shelf GL5 gear oil for my big twin's transmission? I have seen the great reports on Spectro 6 speed oil offering although this is not readily available in my area. I would like to use a reputable brand such as Mobil, Valvoline etc. Additionally.... What is the desired weight such as 75w90 or 75w140?
