We opened this PE based on a single complaint of rapid fuel expulsion while re-fueling from the owner of a Buell 1125CR.After opening this PE, we contacted other owners, Buell dealer service departments and monitored activity of various Buell-related web forums.While Harley Davidson (Buell was a subsidiary) has no owner complaints, it did receive four warranty claims related to this issue.Two involve the fuel line check valve, one a pinched fuel vent hose, and one saturated charcoal cannister due to over-fill.Currently, the data does not indicate a trending safety defect exists.We will continue to monitor this issue and take action as appropriate.
