One of my buddies just bought a 2000 mxz 700 with 6400 miles. It has k&N filters instead of an airbox. I rode it the other day and noticed it only revved to 7700 RPM's. Is this normal? What d ifference will a stock airbox make?
You can adjust the rpms by moving your clickers on the clutch, I would go up one number!
