You guys that have a Harley that runs too hot with dyno have got a problem more serious than the stinking oil. Or you bought the wrong motorcycle.

 

Now that the MoCo has recomened changes at 5k intervals - it only makes sense to use the stuff. I have always used Mobil 1 15w50 - not the V-twin high $$$$ stuff, and after 100k on three different models, well if it ain't broke don't fix it.

JMHO
