CB450 Mikuni VM30 or VM32 ??

1972 CB450

I’m contemplating on upgrading to the Mikuni carbs, but wondering if anyone has experience running them? VM30 or VM32? Why?

I’ll be running lightly baffled straight-through to exhaust just past the rear axle, and pod filters.

There are pre-jetted kits out there for both sizes, but I’m thinking that VM32 for an otherwis stock engine is too big?

Can I get away with VM30?

get these and rejet lol

These look cool, but don’t know too much about them? Do you know what size they are?

Also, after I get the new boots, jets, filters, and whatever else I’d need to fit these, I’ll be nearing the price of a complete Mikuni VM30 kit

Do you have experience with these Sudco carbs?

Here is a list of everything that comes in most kits...

2 Pre-jetted carburetors
2 High Performance Pod Filters
Model Specific Throttle Cable <——
Mikuni Tuning Manual
Custom Designed Billet Manifolds w/Gaskets
Heavy Duty Manifold Adapters w/Clamps <——
Heavy Duty Fuel Line w/Clamps
Extra bag of main and pilot jets for fine tuning:
Extra Mains: #175 & #195
Extra Pilots: #30 & #40

Does anyone know:

Is it possible to to use the stock manifold adapters on Mikuni carbs? Or do I need the new “heavy duty” ones??

Also, do I need a special throttle cable? Or can I use the OEM Honda throttle cable?

the heavy duty manifolds will be mikuni spigots

i wonder why if they are prejetted you need a bag of jets lol

and they are 175 and 195 that is a big jump around what happened to 180 185 190 same with pilots 30 and 40 is a world apart

30 32.5 35 37.5 40

better read the feed back on some of these kits and if they work
