I have a 06 10r, and i just gave it its first oil change, 10-40 petroleum oil reccommended by the mfg in the manual for oil type (for motorcycles of course). and the kawasaki dealer said to put in synthetic. they said for the first oil change (or 2-3k miles) is change it to synthetic. I said what!? he said, yes, ask all your freinds, the best thing you can do for your bike it to change it to synthetic.
So im asking all you guys. I think they are full of crap. what do you think.
