so you think its worth going from 50mm to 52mm will i see more power. the bike now has a 50mm bbk with stock head its a big body 50cc so it slow to start with it already has everything else that can be done racin clutch. 20mm car  main jet big variator free flow air filter racing cdi hot coil ect |
