I always get my oil and filter at NAPA. I use the Wix or Napa Gold and Amsoil 20-50 Motorcycle oil, both available at Napa here. They can also get me any of the filters listed in the Tech Vault if I want to wait a day or 2.

I learned all I need to know about life by killing smart people and eating their brains.
