I fitted bike carbs in 2005, the carbs came from a Suzuki GSXR 750.
They are not too angled so sit nicely under the bonnet , At that time I installed a Facet electric fuel pump + filter king regulator set to about 1psi.
Anymore pressure and they will flood ,most people fit an electric pump from a motorcycle as they have a built in pressure cut off rely on flow rather than pressure.
I have a bike pump in my shed ready to fit but the Facet setup has given no problems.
The standard main jets were .112 I drilled them gradually and ended up at .150
