I've never used the "jack screws" to support any weight. Mine are back way off so there at least 1/2 " above the floor. The weight of the bike is supposed to be on the 4 wheels ( in my opinion).
As for the one wheel lifting up.. I agree with the other poster that you've got the jack positioned where one of the four contact points is not even with the other three. I use the "jack screws" only if I want to prevent the jack from moving so I screw them down till they contact the floor once the bike at the desired height..

That is a caster issue. They are easily replaced but you may try spraying a good lubricant into the bearing.

Back off the jack screws till they don’t touch the floor when the bike is off the ground and you should be good. I only drop them when I’m locked in position and back them off when not in position. From the picture, it really looks like your screw is holding all the weight on the side your caster is off the ground.

Those threaded anti roll adjusters aren't made to support a nearly 1000 pound motorcycle; in fact, they aren't designed to support ANY weight. They shouldn't even be within reach of the floor when jacking the bike up; hold onto the bars when jacking if there's a chance of it rolling around. Once it's up and in the locked position you can screw down the adjusters just enough to contact the floor to keep the bike from rolling. Having ANY of the caster wheels off the ground and those adjusters bearing the weight of the machine could result in it breaking off and the bike shifting/falling over.
While we're at it. That bottle jack should only bear the weight of the machine long enough to get it to the height you want and lowering it onto the locking bars. NEVER depend on the bottle jack to support the machine longer than is absolutely necessary. This especially true when the J&S bottle jack is made in China.

I have had my J&S jack for 5+ years and never had that issue. For one, it looks like the "jack screws" are uneven. Second, I only use them to keep the lift from moving. Im pretty sure their not supposed to be lifting the jack up

Okay. time to eat some crow. I spoke to J&S today. Stupid me, I had the safety stops to far/deep into the floor. I don't know what I was thinking because I've had the jack for 3 -4 years now. Also, I needed new rubber boots so they don't damage my bike.
Guys, I really appreciate the help. I definitely had a dumb moment.
