V-Max Full Power Guide
The frame and engine number are two important pieces of information to identify your VMAX. Table 1 shows different frame numbers and engine numbers sorted by different specifications. Table 2 is a list of carburetors settings. Numbers used for European V-Maxes are not listed here. As evident in the table, the real full power is achieved by North American specification. With proper modifications you can unleash the full power of any limited power version V-Max.
