How to synchronize motorcycle carburetors ?

[@nicolashoyt5341]

I'm in the process of designing a turbo setup for my 94 magna and I was wondering "If I put a boost gauge on it with vacuum will the needle shake too much?" literally this video was the first one that came up and answered my exact question.

thanks mate for the info and video as I am about to try and do one own cb1300 and VT1100..be lost without your video,,,all the best

[@greggosling2807]

Must add ensure ypur vehicle is at operation temp and always use the carb/body that already has the vacum as the standard one to match to

Thank you sir❤

is the internal diameter of the adapters important? I have 4 adapeters of the same type, but due to manufacturing imperfections, its internal diameter is not the same in all 4. I can appreciate this fact by blowing inside with mouth; some are more "free" than the others.. thanks.

Thank you, Sir for the great tutorial. One question: Do we have to have to motorcycle warmed up at operating temperature before we start synchronizing the carbs?

[@wsu1232]

yes you should warm up the bike first becuase RPM can change if its not warmed up first

please tell me where I can get some those little regular valve that is used to reduce flutter/fluctuations in the vacuum gauge. I can’t find them on line. I’ve use so many different word variation in the search but no luck. What are they called?

Excellent

What are you adjusting on that carburetor to move that gage ?

[@digdougedy]

You are adjusting the screws that alter butterfly valve angle on the carb... Not the fuel jet screw.... There are videos on YT that show the screws better on in line 4 engines..They tend to be philips screws on Japanese engines, where fuel screws are normally flat heads..

Gotcha thank you for your reply 👍​@@digdougedy

There are 3 adjustment screws but 4 carburetors. Why can nobody just explain what does what? It would be self explanatory if there were 4 for 4, but there are 3 for 4.

[@skeetskeet55]

One of the 4 carbs is the "set carb" . This means all the other carbs should be matched to the set carb that doesn't have the screw.

My bike only has two carburators. How would I go about it then? Just plug two hoses?

[@digdougedy]

yes

👍👍👍

[@johanhildingsson1342]

Hi Thanks for a very nice video. Is there any chance of only doing two carbs at a time? We order the tool for four carbs but we missed there was two m5 and two m6 bolts and the m5 do not fit.

Well, went to the Amzaon link and it says "unavailable"....guess I won't be buying it!
