New here need help !? Bbk questions

[modded50]

Hello I have a 2021 Wolf rugby it’s 49.6cc and I need more power
Can somebody please help me out what’s a good bbk 47mm 50mm? And if I just get a 47mm bbk can I use my stock head or do I need a bigger head? And can my stock carburetor I think it’s 20mm not sure though or do I need to reject also ? And I’m not sure if I can reject this carburetor
Thanks

You should probably have this post moved to the tech questions forum where they cover such questions. BBK requirements have been covered extensively in that forum.
