Man, that timing couldn't be worse. You're looking at ordering parts, waiting around, doing the actual work, and by then everyone's already back from the rally posting photos. Rentals are tricky because most places cater to tourists who want a weekend cruise, not someone doing serious miles with a riding group. I've heard decent things about what EagleRider's got in most cities, they usually keep a range of bikes so you're not stuck with just one style. People also use Twisted Road when they want something that isn't just the standard fleet bike, more personal selection that way.
