I was going to weigh my new bike the same way before I do any mods. I have two bathroom scales. Glue a few sheets of quarter inch plywood of different lengths together to make a ramp about 15 inches long and place a plank between the scales to roll the bike down until you have the front wheel in the middle of scale A and rear wheel in the middle of scale B. Hold the bike balanced and ask someone to photograph the scale displays, add both weights for total. It had occurred to me that I might use a third scale to place the side stand on. The bike would remain perfectly still and I could walk around to view all scales. However, this might introduce forces on the scales that aren't perfectly parallel to the force of gravity.
I've already tried balancing my new 14R with my fingertips on the bar ends and it's easy. I've also noticed my bathroom scale tolerates a reasonable amount of movement while I stand on it without the display changing. I don't think it will a problem to get steady readings from the scales. I may try using the third scale just to see how it compares. If the side stand scale were elevated so the bike was not leaning, three scales should result in the same total as two. ...you would want to keep a finger on the outside bar end to make sure the bike doesn't tip over though. You'd still need someone to photograph the scales for you.
Any bike is going to be weighted more to the left or right off of axis A, most bikes probably lean forward off of axis B. Most floors are not perfectly level, the bikes going to lean a half a degree or so any way you balance it. Most accurate would be a hanging scale with all the weight focussed on one point perfectly parallel to gravity. I doubt any of those factors would account for more than an ounce of discrepancy. Obviously I'm splitting hairs.
I bought the Taylor glass digital scales from Walmart. They're about 25 bucks each. I've seen them used to weigh a ZX-14 here on this forum, they should hold 2-3 hundred pounds each without a problem.
I've noticed with scales designed for lighter weights that the display changes if you leave the object you're weighing on it for more than 30 seconds. Apparently the springs in the scale compress and indicate a higher weight. I'd be ready to roll the bike back off the scales so the scale springs can rest before doing a reweigh. I don't think a reweigh will be necessary after you get the technique down. The main thing is holding the bike balanced and that's not hard, even with my stock 14R.
