Go for it, I do it every now and again. Heck some people talk like motorcycle engine are delicate swiss watches, they are no more prone to failure than any other engines. When I had my Vulcan 750, I made my own snthetic blend with Rotella mineral and synthetic.

For interest one is Shell Advance SX 4 stroke synthetic fortified and the other is Shell Advance VSX 4 stroke full synthetic. |
