Well the Gixxer 1K is broken in 2200 miles...
So back to my usual adding 1 oz 2 stroke or top oil per gallon.
After 10 miles buzzyness at cruise was greatly reduced
Mileage went from 39 MPG to 44 mpg this is brisk cruise not all out hauling.
This practice has had similar results on my last 4 bikes
So if you would like a smoother feeling motor give it a try...
I don't know if it does anything else but its easy to
extrapolate (sp) other benefits
