I have a kawasaki 2006 650r with 19k miles and have run only regular oil from the dealer(dealer maintained). Is it too late to change to full synthetic?I'm also getting a 929 that supposedly has used HP4, that should be ok.

I know in cars its a no no to change to full synthetic after soo many miles. I once changed the oil on an older car that I had when I was younger with 190k miles with full synthetic and oil leaked all over the place...needless to say that car died right after reaching 200k(91 mitsubishi eclipse gsx)

 

19k aint shyt for miles. youre fine.
