I would ride the bike to the next rally, right into the trader village directly to the Mothers stand, where they are always wanting to demonstrate just how good there products are, tell them if they bring the bike back to concourse condition then you will consider taking on a franchise 
That reminded me of a hoary nasty trip. Was on a long trip on a really nice Road King. Had come across the top of the Great Lakes and dropped out of Canada back in to the states at Champlain. Wandered around the lake some then headed east across VT and NH and rain. And rain. Finally in Maine on the way to Ellsworth and hit construction on US 2. No road surface type construction. In the mud.
Traffic was throwing mud and muck everywhere. Wheels schwimming and schwishing and sliding. Had to drop back a 1/4 mile behind car in front just to keep from being blinded by his whale tail of liquid road goo. It went on like that for 20 miles.
By the time finally got in to Ellsworth the bike and I looked like the Pillsbury Doughbiker. Just one huge mud ball. There was a rally in town. Some guys at the rally were doing bike washes. Headed there first thing. Gave them their $25 and an extra ten for hosing me down. Pulled on some dry clothes behind a tree and wandered the rally site (shopping center parking lot) for a couple hours. They did a damn nice job on the bike too. Wouldn't take a tip either. I like Mainers.
