In 04 just after I bought my bike my local dealer didn't have a 10W40 in the Kawasaki oil, the owner told me any "good quality" oil was fine to use in it. I used tech 2000 10W40, and 20W40 for about 20,000 miles. Now I use castrol oil and the wt depends on the temps, (10W40 in cool weather and 20W40-50 in hot weather.
After th tech oil I tried the rotela and didn't like the way it shifted with it in the bike, I tried the synthedic and developed oil seeping around some of the gaskets, thats when I went to Castrol. I now have 35,600 miles on my bike.
So the choice is yours as to what oil to use, but I agree the key is changing it reg and often. I change mine between 1500 and 2000 miles.
Today is the first day of the rest of your life.
