I have a bicycle hand pump along with a tire plug repair kit (string type) tucked under the right side panel by the battery. I also carry a DynaPlug 12VDC pump that plugs into the SAE plug I have attached to the battery. I have used both, never had to seat a bead with either so I can't attest to which works best for that.
I used the Slime pump for years and it served me well even seating the beads on 2 tires but the size of the case made things harder to stow and I upgraded to the Touratech model. This thing is tiny compared to the Slime, I hope it works as well.
I bought one of the motpump air shots. Haven't used it yet, but I've watched a friend use his motopump at several rallies, always pumping up everyone else's tires. I keep the motopump, tire plug kit, and some other tools in the bottom of one of my side cases. I have two SAE power plugs attached to my battery. One routed to the instrument panel for phone chargers and other accessories. One SAE plug is attached to the frame so that I can easily hook up jump boxes, pumps, etc.
I believe there is a discount link for advrider members on the advrider site. It dropped the air shot from $60 to $50.
I previously used a foot pump made for motorcycles. It took forever. Last time I seated a bead while offroading my minibuggy, I let my cheap slime mini air compressor pressurize the tire while I smacked the sidewall. It popped on dry, no problems.
