Page 441 in the owners manual covers an important point that may be related. The towing load chart lists a max tongue load of 500 lbs. If the configuration of your trailer and the weight and position of your motorcycle placed too much weight forward, that could be a cause of the symptoms you describe. I do a lot of towing/ hauling with my farm equipment with much higher weights and larger trucks. I have for instance placed a tractor too far forward on my large trailer and had very bad handling. I have had to stop and re-position the tractor further back on the trailer. When loaded more closely to recommendations the handling was excellent. The weight was not the problem, the load balance was the problem. We don't usually have immediate access to scales to exactly set our loads so we have to sometimes work by feel and experience to get in the proper range.

Good luck with your rig.
