After filling my bike from both sides and trying the McCuff too, I've concluded the best approach is to fuel my '09 Ultra from the left side. I not impressed with the McCuff either; I've sloshed out more gas with it than using nothing, so it's now collecting dust in my garage. I now fill from my bike's left side and place the nozzle in the tank pointing to about the 2 o'clock position. I can fully fill my tank if it slow down the nozzle rate towards the end and then click it just a few more times. However, some nozzles are problems no matter what approach you take.
