Hi everyone,I just wondering what size the c90 main jet is i.e. 5mm or 6mm, also what size i.e. 85-90? My plug is always black so thinking I'm running very rich and only 45mph!

First up, is the air/fuel mixture set correct? Unless the carby has been apart, jetting would not suddenly turn the mixture rich.

Most likely the choke cable has kinked and staying on slightly, or the air filter is old or not a Honda one.
