Left-sider too.
One of the advantages to left side mount is that I use my momentum to upright the bike (to disengage the side stand) as I'm mounting.
If you put your right foot on the right peg and then swing your left foot to the left peg, then you're sitting on a bike with the stand still down! You then have to take both feet back off the pegs to put up the stand.
This has been an amusing, interesting, intriguing, and thought-provoking thread for me. Mounting the bike from behind by doing a broad jump and watching out for the handlebars is one that comes to mind.
One that I haven't gotten a handle on yet is how the crown of the road is related to parking, mounting, and dismounting a motorcycle. I've only been riding ~39 years now, but I haven't yet encountered any necessity nor opportunity to park
on the road. Only way I can visualize that happening would be a LEO or emergency responder at the scene of an accident, and I've never fit either of those categories, although I realize there are members of the forum that do.
I sometimes mount my ST from the RH side when it's parked in the garage. I have to park it on the CS because of space considerations, and it's often easier to mount from the right because I have more room to do so. When parked on the CS, it makes no difference to me which side I mount it from. I'm in the habit of always applying the front brake when I mount up, and can easily do that with my right hand from either side.
I found this post both amusing and thought-provoking, as it implies (at least to me, though I may be misinterpreting it) that one can put up the side stand with the right foot on the peg. Since one can't shift into gear with the side stand down, the only way I can visualize this achievement would be to tilt the bike upright, raise the side stand, quickly shift into 1st and take off before dropping the bike, all of which would require some really fancy acrobatics. I would like to see someone try this sometime (from a safe distance, of course). The outcome would either be amusing (although not to the rider who just dropped his bike) or amazing (if he/she actually succeeded).
Thanks to everyone who responded to this thread for the entertainment value,,,
