Last October I had the failed fuel strip changed by the dealer in Canton, MI and since then a friend noticed oil seeping out from the RH side of the air box, where the tube exits the air box, to the engine. I asked the dealer if there was a possibility if they had pinched a vacuum line when they reinstalled the tank and they were mostly silent. They also said not to worry about it and there was a drain plug in the bottom of the air box to drain any oil that did accumulate. I couldn't find the plug, couldn't get the air tube to separate from the box even with the clips pulled and finally gave up. I wiped it off, drove another 50 miles and the oil reappeared. Anyone with any experience in this issue?
