Sounds kind of familiar, I had a similar (tho not exactly the same) issue after I fitted my Tail Tidy.
Symptoms I had were that the bike was stuttery (like running with the choke out), and at 7k revs it would pop the exhaust and lose power.
The difference could be that the carbed curvy behaves differently than the injected pointy when the fueling gets messed up,
Basically while fastening the undertray back to the battery box, I managed to disconnect the CKP connector. This has a white and a green wire in from the front of the bike, and a black and a black + white wire going to the rear of the bike.
This is the connector for the CranK Position sensor.
Other thing that occurs - could you have a stuck/sticky choke?
