A follow-up on this....
Mine was in the shop for weeks for this issue. It was highly repeatable and the techs verified there was a true problem. Ultimately, after going back and forth with DNA and trying a few things, they best determined it was low oil pressure to the clutch area. It should be 1.1-1.2 bar, but mine was about half that... according to two new V4-speciifc gauges that each gave inconsistent readings.
The oil pressure apparently can be adjusted with a set screw that sits behind the front sprocket, and so they set mine identical to another V4 which never exhibited these symptoms. They also blew out the oil plumbing with compressed air, in case there was a blockage, perhaps from some stray gasket material.
After all of this, they tested it for half a week and the issue seems to be resolved, and I've had it for a couple days with no issues either.
They did mention (and I agree) that if the issue reoccurs, its no cause to stop riding the bike (it does behave normally after a few minutes of riding), but to let them know and they'll continue troubleshooting. They also mentioned they are getting complaints of this sort from a few other dealerships and it seems to be an oil pressure issue.... not to the engine, but to the clutch area. They claim there is no risk of engine damage, but the clutch plates may not be getting wet enough with oil for smooth initial engagements into fist gear after sitting overnight or longer.
Aside from this issue, my bike behaves perfectly and it's a fantastic mean machine. I have 1,100 mile on it, and LOVE it!
