You could probably work it out with A LOT of experimenting with the porting, carb tuning, fuel mix, ect, ect. It's probably running just a little rich, which is better than running too lean. If it has a good pull all the way to the top end I'd leave it alone and just enjoy the ride. Just my humble opinion.
I would be more worried about the vibration. I would replace the chinese mount studs and nuts with a better grade and make sure they are TIGHT.
