Hi all, I'm a new rider been riding for a few months, bought a 2013 Stryker and I love it!!! I had a quick question, I noticed a hose hang on the side of the radiator on the left side of your sitting on the bike, it hangs about 3 inches below the radiator. I was just wondering is this normal? I was assuming it's a drain hose but wasn't sure. Thanks in advance for the info.
