Hey guys.
Since three years I'm running my 1980 Sporty with the SAE 50 motoroil.
Does anybody know if there is another oil I could possibly put in it? Like a 15w40 or something else?

I hope the oilclassifications are the same in the states as in germany.

My Ironhead didnt like the 40 weight. Just a little to thin I think. Stay with SAE 50 weight.
