converting single sbn 46's to run as duals

[yamijumpn]

well maybe my word choice in the search isnt the best so I am not finding the information I need.

What is all involved turning two single sbn 46's to run as duals? I am going to start with fresh jets, N/s, and rebuild kits on both. Both are silver sbn's.

Also is there a difference between the sbn from a wetjet and one that was right from Mikuni?

@JetManiac should have the parts needed

The problem with doing this is there are several different versions of the 46's and 44's not counting the wet jet 46 which is altogether a different carb. The bolt spacing is different. Honestly, unless you can source identical 46's I would find a set of dual's.

 

[yamijumpn]

yeah that was my main worry. sounds like its time for some braap jacks!

Dual SB46 Mikuni install, uses a lot more fuel than dual 38's . I used new carbs, still had to change jets, n/s, and springs.

I may be selling a set of very clean dual 46s if you were interested. Price would be $350. @jo5hi3 and I just installed brand new oem mikuni throttle plates and throttle shafts, along with a JetWorks zero backlash coupler. I could probably jet to you specs...i have most jets.

@yamijumpn this would be a good option for you if you're set on 46s

Yup, and ducky's carbs have flame arrestor adapters and brand new oem needle and seats...

What carb linkage is that and where do I find it?

You can find it at McMasterCarr...but they arent cheap at all. More expensive than a JetWorks linkage.

I think thrust also has them. Not sure if they are different or priced any different.

you have the actual name of these. I hate Mcmasters website for searching odd ball things. Its always named something I never think of.

Took me longer to find this thread again than to find this link.

 

[yamijumpn]

yeah simpler than i thought. was looking under throttle coupling. thanks @Big Kahuna

Price increased quite a bit recently, and I still had to source my own ss screws to replace the reg steel screws . Also used a 8mm drill bit to enlarge the 5/16 bores slightly.
- I just like really - not somewhat- zero backlash , clamp on, helical beam couplings. You can buy something similar from Amazon, made you know where, proper 8mm bore but not quite as flexible for less than $6.
