Originally UK spec would have been 40mm Webers. So if they are 45 might be a bit fluffy at low revs but if you take the better breathing / tuning route they'll be potentially more powerful.

Carbs of any size will also sound more fruity, whether that is good or bad is up to you.

Spica is reliable and powerwise I am told matches the standard carb setup. Your only issue is the comparative lack of UK service support if it needs work in future.

I could imagine someone switching from Spica to carbs, but probably rarer the other way round.

To be honest I'd stick with what is fitted unless you have a specific problem.
