Dual Carbs Linkage

[Ahmed AN9]

Which one is better and reliable to link SBN 44's?
1- Mikuni carb linkage.
2- Jetworks zero backlash linkage.

@THRUST linkage all day. No backlash and allows the tiniest bit of angle movement up down side to side

 

[Ahmed AN9]

Does it require to cut the shaft to fit the linkage in?

 

[x2mafia]

yea I think they all do. The shafts are to long for the carbs to sit at the 118mm apart spacing or whatever it is

That looks like a CNC motor shaft coupler.

Will that fit on the carb shaft..?

Will that fit on the carb shaft..?

throttle shafts are a hair smaller than 8mm, so no it wont fit. you could probably drill it out to fit. not sure what its made out of or if its springy enough to work.

now is this a butt hair or a c*** hair?

 

[TheBuzzard]

I steer clear of anything with butt hairs

I have never used them. I came across them looking for coupler nuts.

Here are more sizes.

View attachment 332573 I've been using these high priced couplers for 25 years. Still need to drill them out from 5/16" to 8mm (easily done hand held) and also change the 2 crappy socket head cap crews for ss ones. Expensive but very reliable.

I would like to take this apportunity to have your advices. Am thinking to buy dual SBN-R 44's (Riva modified) carbs which come with 2.3 n/s and 115g spring so the pop-off would be at 22psi. Riva recommended to use 110-115 main jet and 120 pilot and as I understand , these jettings are reversed and will affect on low-mid range (freestyle) setting but as I would have a powerband from mid-top almost recreational/WOT, Do I have to use this setting or I would have the opposite jetting 120 main and 115 pilot?

 

[Ahmed AN9]

Anyone ???

Overall jetting is the same either way. But the fuel curve changes slightly when you go back and forth between reverse and standard jetting. Very small change in your case

So, I might only switch the jet size 120 main/115 pilot with the same pop off
