When I crank the wheels by a side I have different aperture.bbsilver - 3/2/2005 6:34 PM
You shouldn't have to remove the wheel to get to the lights. Just crank your wheel to one side. There is a flap that gives you access to the light on each side.
Living on a farm. That explains the air filter. Since you live in a dirty area, I would suggest changing the air filters more often than the manual recommends.
