I run 20W50 Amsoil but at 65º F my bike never breaks 200º now when it is really hot out I have had mine up to almost 250ºF on my trip to Fl this summer for instance. It was well over 100ºF out and even at highway speeds it was running about 225º.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
