So while changing cables on my buddies V-Star 1100 we noticed a little puddle of oil in the airbox under the tank. We didn't really think much of it at the time. However upon further inspection of my own 1100 I found that the penetrations through the airbox leading to the carbs themselves were oily and had an oily buildup. When I opened my airbox there was a larger puddle, approximately 4 oz of oil. Which brings me to the question 1. Is oil in the airbox a normal occurrence with these bikes? 2. If so how much is an acceptable amount? 3. How do I keep it from leaking?
