Just my opinion - but you asked. I was able to find some ebay and craigslist 1200's cheaper, and without the mechanical defects you have listed. I know you like the bike, but "runs great and has hesitation at 2k rpm" doesn't quite go together.
The only thing I see odd is that you say it runs great, but then you say it has an exhaust leak and a hesitation. Those two problems tell me that it doesn't run great. Buyers get skeptical when an ad is contradictory.
