The wiki on for everything about carbs is missing the syncing section. that isn't a problem i found a tool i think will work. I also understand the principal behind how the tool works. my question is:

does someone have a picture of where the tubes need to connect into each of the carb sub-sections? and any other special notes that would help me with how to do this project.

Will this tool work?

Yeah that one will work.

Here's Mine:


Old pic of when I was synching my carbs.


Here's a random pic of some FZR carbs:


See the screws in the bottom of the black intake boots? They are to be connected there. You can use MIG welding tips (.045 is the size I used). Then all you do is follow the correct synching procedure

Hope that helps.

Yeah, that will work. I did a similar thing with tubing that I hung from a step ladder.

There is a brass colored machine screw on each intake boot. Unscrew them and put your brass fittings in there. Here are some pics to help identify where to connect them:



Here is a shot of the tubing that I attached to the ladder:

Awesome! I've been trying to figure out the same information and for the life of me couldn't find it. Thanks for making the thread Cursed and thanks for the pictures/posts guys!

That's why we're here....

Just remember to use a liquid that is not too thin and not to thick. You want to be able to see the fluid moving, but you don't want it bubbling or dancing around too much. Also, don't use anything that could get sucked into your engine and hurt it.

Good point there. I used power steering fluid in my setup. Most setups I've seen utilized ATF as the fluid. You'll also noticed the 6mm MIG welding tips were mentioned as part of the home built setup. That is because thy act as a re-stricter to slow the flow of vacuum down. Most mass produced carb synch tools come with attachments to do this function otherwise the fluid would almost immediately be sucked into the motor

I use sobe bottles for my sync tool. I use brake fluid in mine though. But I will fill one bottle about 3/4 of the way full, and then split that between the two bottles. Theres still plenty of fluid to see whats going on, but if it all gets sucked into one bottle, there's no risk of it getting sucked up in the engine.

2nd. I used water cause I didn't have these fine folks here, and I had the GF with her hand on the kill switch. But the 3/4 thing works best. Also if you don't want to get the mig screws, I went to oreillys and got some 6mm grease fittings(box of 12 for 2.09) and just drilled out the ball bearing. The tube doesn't want to stay very well but that's an easy fix with a zip tie. It's easy.
