RGS-SFC Stock Airbox to Mikuni RS36's

snap Simon.

from the Mikuni manual

& regardless of any tech diagrams, i've changed a few pilot/idle jets over the years and i can recall what happened.
so i reckon what Cam stated is very misleading.
  just trying to be helpful.  no points scoring for me.  & i just might be wrong again ??  ho-hum  ???
  cheers,  Mark

As far as I'm concerned, pilot jets are always flowing fuel, whatever the throttle opening and so size does matter!

agree 100%, they just don't shut off when the throttle is opened



 
This is how I fitted the original rubbers on stock airbox with the Mikunis. Like Keith said, they need to be pushed into the airbox a bit and, in my case, the LHS one had to be slightly adjusted (cut).

Are these adaptors I see on the ends of the carbs where the rubbers touch?
 
Here we are still maintaining and adjusting Carburetor's when Fuel Injection is Superior using  EMC Modules, High Pressure Pumps and Injectors.

To Bad one of us can't put together a workable Fuel Injection System for our old 2 and 3Cyl Breganzies.

I particularly like the Jetronic Lamba FI System and loved the old Mechanical Bosch FI paddle fuel distributor.

Have a look at Steve Battisson's website (Breganzane)!
 
Had a working system on a triple way back in the mid '90s at Moto Witt.  Due to the lack of suitable components, much had to be manufactured, wasn't financially feasable.  Built the complete intake system ourselves.  Was an eye-opener though, raised power of the bosses' worn out and battered 120? hack from just under 90 to a whopping 112hp.  Shows how hit-and-miss carbs can be.

Would be a different picture today, lots of stuff on the market that can be adapted rather easily.

Here's a pic of my own rather humble effort, lost further interest due to a lot of things...

Piet: Nice FI Log you've designed.

Why FI isn't feasible for our Breganzies.

I kinda think that our cylinder head intake ports are too small and rely on velocity for atomization where as FI needs Big Intakes Ports designed to dump Volume and reduces negative pressure above the pistons.
