To all worried about synthetic oil:
In regards to seal leakage, that was somewhat true in the '70s when they were relatively new because the additive package did not contain any seal conditioners, and some seals did shrink and dry out a bit causing the oil to seep past them. All modern synthetic oils contain seal conditioners to protect and maintain them like conventional oils do.
Regarding clutch slippage, this is another topic that concerns some people. Synthetic oil does not promote clutch slippage under normal use; normal meaning anything done on the street. I used to drag race a Vmax that would occasionally slip after repeated, super hard launches on the strip, so I switched to Kendall conventional oil. The same thing happened with the Kendall after repeated launches. This was on a brand new racing clutch. Alot of what people think is clutch slippage is actually the rear tire hazing, or breaking loose slightly. I proved this by using a race computer, a white stripe on the tire, and a video camera.
Also, all high end race teams in Superbike, MotoGP etc, use synthetic oil. Do you really think they would tolerate a slipping clutch?
After your 'Busa is broken in, do it a favor and use synthetic. It flows better, protects better, runs cooler and lasts longer.
Thanks for taking the time to read this!
