I have an 05 SM and am interested in the Vapor for the tach function. But I was wondering about the odometer. If I have several thousand miles on the bike, and install a Vapor, can I manually set the odometer on it to match the actual mileage? And more importantly, if I were to go back to the stock speedo unit and sell the bike after several thousand mile of Vapor use, I'm assuming there is no way to show an accurate odometer reading on the stock unit? In today's legal world when an accurate odometer reading is such an issue when buying/selling, I'm just wondering if removing the stock odo is going to cause headaches when it comes time to sell.
