Hmm. Since I have the Smuggler seat, I do not have the grab rails anymore and so I have to reach lower, using the saddlebag guard.
I use a rocking motion for a few cycles then use my thighs and 190lbs of direct pressure to get her up.
I don't mean to be sarcastic, but there are two 'mistakes' I've personally witnessed watching GoldWing Owners put their bike on the center stand:
1. The bike was in gear
2. The person 'helping' them on the right side of the bike was holding the front brake - "for safety."
Best of luck!
