Just a quick query.
If you were to replace slide carbs with CV carbs would you be looking
for similar size or larger?
Any experiences swapping (either direction) between slide & CV?

What bike engine are you thinking of doing this to?
I would have a look at parts fiches/specs of bikes that went from slides
to CV without making any other changes, such as a Z650. I would strongly
suggest sticking with a stock CV airbox for the model in question, or
something really close to it. Many CV carbs really don't like individual
pod-style filters.

Laverda triple. Maybe a Laverda twin as well.

Never thought of that

Will probably stick with the stock airbox - no point in going to
civilised carbs then sticking pods on.

What's the motivation for doing this? I'm a firm believer in keeping
things stock if at all possible. I'm currently undoing a number of
'improvements' to the carbs and airbox of a GSF400N. It seems a lot of
people never heard of Hermann Ludwig Ferdinand von Helmholtz.

Improved fuel economy. Better power. Getting both sounds unlikely but
it's the results reported by the people I know who've stuck more modern
carbs on their triples - I've seen the dyno charts & I've ridden with
some of them enough to know that gas stops have got further apart since
the carb change.

I suspect the only reason Laverda stuck with Dellorto pumpers as long as
they did was because they couldn't afford anything more modern.
Stock has a lot going for it but it's a bike for riding so modernising
where appropriate is useful - already done the brakes, I've got modern
switches to wire in & CVKs are well cheap on fleabay. A proper ignition
to replace the Bosch horror isn't so cheap :-(

Don't think Laverda had when they were building triples. I'd love to fit
a bigger airbox in but then I'd have to find someplace else to stick the
battery
