Aside from the carb rebuild, have you changed anything else? An '09 might need the CVT disassembled and the rear sheave dismantled/cleaned/re-greased.

Is the bystarter plug connected? Plug is over by the starter relay, above the spark plug. If not, it'll be overly-rich and run poorly.

Have you checked the air filter?

Lastly, budget Vino Boost Recipe:

- Polini Blue Spring for Zuma 125
- 12gr rollers in the variator
- Main jet to 100 (Mikuni) and UNI red filter for Vino 125
