HSR48 (TM48-2) Data Set
Mikuni recommend that engines producing more than 120 hp should use an electric fuel pump at less than 4psi with the 2.3mm float valve assy
The carb can be mounted using the HS42/062-48 manifold. This should fit an S&S ‘G’ manifold but it will add a little extra to the total length of the installation.
