Herc770, I tried to find the "hoist" you were referring to in the Whitney catalog but couldn't find any pic with a Valkyrie. Therefore, I'll take a stab and ask if the pic I've included might be what you are referring to...or something similar.
If this pic resembles what you mean, it's a lift I've used for several yrs. Mine is a Larin brand lift. It works very well. I do use a lift adapter that's made out of square tubing. The adapter bolts to the bottom of the bike and helps stablize the bike to the rails of the lift. I also use ratcheting straps to help secure the bike to the lift eyelets.
If you do a search for lift adapters, many on here have made some from various thickness of wood; plywood, 2x4s, etc.
If you could be a little more specific about what you're looking for, or trying to do, please let us know. The VRCC tech board is filled with knowlegeable wrenchers who can help you out.
