nc30 bigger carbs

[georgenc30]

The nc30 has 32mm carbs so what if i put a set of 34mm carbs on it from the vfr750fg/fj that model was made at the same time as the nc30.
Will i gain anything over the standard carbs?

Wouldnt the jetting be out its not quite as simple as throwing larger carbs at it im sure. what mods have you got on the bike at the moment?

i thought the carbs on the nc30 were rather big for the bike anyway not sure of what advantages there are to be had of going any bigger

The nc30 carbs probably are bordering on too big for the standard 400, but rlr do bore them out to suit their mega-hp high flowing engines.

The 34mm carbs could probably be made to work fairly well, but fitting them would be a nightmare, they wouldn't line up with the intake ports at all.


The 750 34mm carbs are a similar design to the nc35 carbs (earlier vfr750 36mm carbs are similar to the nc30), pity there's none of these available in 32mm!
