Hi everybody

What are the best plugs for a 1972 750 sf VHB 30 and  small valves N2C or N3C ?
In a other hand the mixture seems to be too much rich with the 125 main jet can I run a smaller one 120 or so ?

Went to the Troffeo Rosso yesterday and saw lots of Laverdas and the V6, great moment !

Safe riding
 
Sergio,

N3C should work fine with stock pistons and cams.  Before you go swapping main jets, check if you have the corrrect needle and needle jet, should be V3 and AN265.  V6 also seems to work well in some cases. 

Worn or corroded needles and needle jets will cause rich running through the entire rev range.
