I really enjoy these detective type investigations. Very Dan Brown. Can't wait to see how this one pans out.
Weight shouldn't be that much of an issue, plenty of us big fellas on Fazers and same goes for jack up kits, but it's interesting that the Dynotec guy said it was all over the place and couldn't offer a suggestion. That's really odd and it sounds like it won't be something simple.
If it's done around 20k miles, the rear wheel bearings might be on the way out. Yamaha had a duff batch judging by how many fail around that mileage (mine's done 80k on a replacement bearing, so they were definitely a duff batch). Having said that, I'm sure your mechanic would have checked that.
Other things I'm sure he'd have checked - headstock and swing arm bearings, but again, you'll be the first with knackered swingarm bearings, and one that's often overlooked is whether the markings on the swingarm are misleading - it might just be that the wheels a bit skew whiff. Does it feel better on left or right corners?
That's also a good check if you suspect a bent frame. Fazer frames are steel so it should be possible to straighten it if it's a bit bent. All is not lost, we'll crack this Da Vinci Code of a bike yet!
