If you don't like noises the 900 is wrong engine for you. Not sure what you're describing but each engine seems to have a personality when it comes to oil. I did 5 oil changes with different oils in 6k miles and my 900 seems to like Rotella T. Engine is quieter and no clunk when shifting.

Do you use the synthetic or dino oil?

What grade of gasoline are you using? I've never heard any knocking noises from my 900 Custom and I use 87 octane.

Me too, but I really couldn't tell any difference. In fact, it seems to be making a knocking noise at certain RPM's that I'd not noticed before I switched to Rotella. I used the Moble-1 filter, which I wonder if was a bad choice.

I changed my oil at 600 miles and used Honda dino 10w40 with a stock Kawasaki filter. I've never heard any knocking noises out of mine, ever. I hear a lot of belt noise, but I think we've all got that problem...
