i have a 2005 sposter Harley Davidson 1200. what is the best kind of oil to use on it?

Hands down......AMSOIL 20/50 MOTORCYCLE oil is THE BEST. It can be run in the engine and the primary/trans. Next best is Mobil 1 and Lucas....MOTORCYCLE OILS. For even better added protection, replace 6 ounces from each bottle of oil with Lucas Oil Stabilizer (SYNTHETIC stabilizer for syn oil, regular stabilizer for regular oil).
Stick with HD for the filter, they are actually the best.

Any two stroke oil as it will only be in the motor til it leaks out.
