I have a lift that I got from Costco years ago. I used it to lift my Gold Wings for servicing, but it also works on the Vulcan 900. I don't have a pic of it, unfortunately. Sears carries one as does Harbor Freight. The Bulldog lift is similar, but VERRRY spendy.
One thing to keep in mind when using a lift on the 900, is that there are all those grease zeros on the bottom of the lower shock mount (or I guess it's the swing arm mount?) Anyway, you will break them off using a motorcycle lift because that is a balance point. I solved that problem by making sure that was lubed, then I replaced (and SAVED) the grease zeros with button head screws. Keeps the grease in and allows the use of the lift.
This is not a jack. It's a lift that has the cross bar supports going side to side under the bike. If the engine is below the frame rails, you can lay a piece of board on the bars so it clears the underside of the engine. Works well, and lifts the bike, at least in the case of my lift, 17 inches off the ground, and includes loops for using tie downs to stabilize the bike while it's in the air.
