First things first. This is an outstanding forum with tons of folks ready to help you with about any question. It has some basic guide lines like filling out your signature line with your bike model so we know what you got just by looking at your sig, that way we know your year/engine, model peculiars. (but I did see you have an 07)Proper forum, oil topics have their own forum(Oil and Lube), not sure why you didnt post it there.
Oil topics are TABOO as there are so many opions that the threads spool out of control yet continue to pop up. Whats the bottom line your after here, saving 20 bucks an oil change? You cannot compare Vic's to other bikes unless you are comparing wet clutch to wet clutch. You don't mention service intervals and I know I just read somethng from KevinX on that. Should easily get 3K maybe 3500 but pay attention to harder shifting or hard time finding neautral. My thoughts, in the end is it worth a 1500-2K rebuild to save a few bucks on oil?
