I use a Slime pump. It's adequate, but it's pretty slow and it does generate a bit of heat. It will fill up a tire to the right pressure, but be prepared to wait a bit. To make it fit better on the bike, I cut the housing apart, removed the pressure gauge, and plugged the port where the gauge attaches. After that it would fit in that little space on the DL650 under the seat and back near the taillight. I don't know if the Vee has that same space or not. I had one of those pen type pressure gauges in my toolkit, so I didn't need the big gauge on the pump. If you look at the photo, that semicircle is where it used to be.
Supposedly the CyclePump is about the best one you can buy (they're available from Twisted Throttle, among other places). They definitely look well made, but they cost around $100.00, which was more than my doo-dad budget would allow.
Whatever pump you get, make sure that it will actually fill up your tire. Let the air out in your garage, and test the pump out there, rather than finding out on the trail that the pump you bought isn't up to the task.
