I'm about to change my bike oil along with a K&N oil filter and was wondering if anyone had any experience or opinion on the Royal Purple 10w40 Max-Cycle Motorcycle oil?!?
This is what i'm talking about: http://www.royalpurple.com/motorcycle-oil.html .. Pretty pricey but it can be found at any Napa stores. A friend told me that that's what he uses in his 94' Ninja and it minimized engine noise and helped to gain a little power. I have used Valvoline 4-stroke motorcycle oil which is ok but I think engine noise is somewhat louder than from when I was using Yamalube.
Any thoughts??
