I have a Touring and the JBQ Bracket. I use the lift from Harbor Freight. I think most of the weight is at the rear, and the arm under the sump just balances it a bit.
The first two winters I stored it on the jack. There's no worry about it tipping. It seems quite solid, WITH the bar locked against the stops.
Last December or so I had a small leak at the front of the sump pan. The bolts seemed loose. Three broke and I replaced all bolts and the gasket.
Now, I don't think it was because of the lift, but still, I'm a bit wary. The bike is a 2010, so after 10 years, it was probably just time for a new gasket.
All in all, those two arm lifts work great!!
