I see what has been said about the first oil change! I took yesterday off to ride and I put just over 100 miles on the new bike. I came home and changed the oil. It looked more like golden metallic paint than motor oil. If I hadn't read the posts I would have been horrified! I fished a magnet around in the oil and only found a small (VERY) sliver of steel. Most of it looked like suspended brass and aluminum. I'll change oil/filter again at 500 miles. I bought a five year zero deductable, full warranty...........Another tip from this site!

That's pretty normal for a first oil change. Just keep an eye on it and be sure it clears up over time.

Hi Zero.
I've got a new ZX as well. Just out of curiosity, what break in method did you use?
