Just so you all know, to the best of my knowledge there is NOT a Belly Pan made that would offer enough support to withstand the weight of the Valkyrie without bending ect.
Most of the pans are only 1/16th inch Stainless, Aluminum or possibly 1/8" Diamond Plate.
I would a 100% agree with you except for the fact I do it at least once a week. When I pulled it out of the box I thought I would have to pull the thing off every time I wanted to jack the bike, it was flimsy to say the least.
Fortunately/unfortunately I am inherently lazy and couldn't be bothered taking it off so I jacked it up with the pan on anyway. I thought I would have crushed it up a bit but it was fine. I gather it is being braced from behind by the pipes and that center ridge. I also spread the load on the jack with a piece of MDF and as I posted above I do all work/washing with the car stands in place, not the jack. 350KG+ balancing on a foot wide jack doesn't fill me with confidence at any rate.
I used to have to put that piece of MDF on and then I had boards in strategic areas to jack it up. It was a pain in the butt and if I didn't have the boards in the right place it would not be too stable. Also I couldn't have the jack back under the water bottle as it would squash it when lifting. I can't be bothered emptying the saddle bags either so it tended to lean back. So lazy haha.
I still use the MDF and can have the rear part of that MDF under the bottle and on inspection it doesn't seem to be squashing anything up. Also the lift is now reasonably level, very stable and I have no issues putting the car stands under now. A few times in the past before the belly pan I have done a few very iffy lifts. All good now, no issues now turning my back on it while grabbing car stands or whatever.
Anyway here is some shots I just took.
This has been up many many times and it looks pretty straight.

A little bit of distortion here but it has hit the road so it is possible that may be the cause. I would not be shocked if it was from the lifting though.

My little piece of MDF that fits perfectly.

Either that or I have squashed the crap out of everything, sounds like my M.O.
