Hi everybody. I keep reading that it's in our best interests to change the fuel lines out every 2 years. My bike was stored for 8 years when I bought it. Obviously it had no fuel in the tank. I pulled the tank apart last week and the hoses and everything looks and feels brand new! I don't know if it's the Factory tubing but it sure looks like it. Still has the click r clamps on it. Should I leave it be or change them while the tank is off? Bike has 3600km on it now and is being stored for winter. Thanks!
