VXR 200 , Bog and very reach after cylinder kit.

Hello,

After installing the cylinder kit (3116208) I get very reach mixture and the scooter will "choke" and bog in mid throttle a especially.

Air box is stock.

What can I do ? (holes is the airbox ?, small main jet/needle ?)

Thanks
Elior

 

What carb ? is choke working ? what cc ?

 

It is a Walbro CV - stock, it has an electronic choke, it is 200cc.
After disassembling it and assembling again - all is back to normal....
