Carb synchronizing

Has anyone evr tried to make their own synchronizing tool?Been doing some research and came across a few people who swear by their homemade tool.All it consists of is some clear tubing,yard stick,tape,and some colored fluid of your choice.Anyone hear of it and tried it?Now I have a single vacuum gauge and was thinking about channeling 4 lines off of it with a shutoff on each line,would that be adequate or do vacuum lines have to work off each other?Any help with this is greatly appreciated.

Yep... Made my own manometer a couple of weeks ago, 4 tubes filled with Automatic Transmission Fluid, (just in case it got sucked into the engine). Came close, when I first started the sync, to sucking it into the carb. But I shut it down and turned the appropriate screw, restarted the engine and completed the sync. I never really got all 4 tubes to line up perfectly, but they are all within 1 inch of each other. That's alot closer than you can get with mercury since the ATF is alot lighter and moves faster. Works great, and since it only cost me about $15 to build, that makes it even better. :wink:

 

DC put up a picture please.

 

Having done the job with a homemade manometer I would think doing it the way you described with only one vacuum guage to be slow and tedious.

Got to be careful not to take too long and overheat the bike when syncing and swapping gauges would take longer.

Have a read here for a description of how to build and a pic of my manometer.

And notice the comment by the next poster after the pic. :wink: l

 

Is it possible to sticky the picture from his original post Sno? Kinda make a spot for special tools and neat contraptions folks have cobbled together that Joe Commonman can make at home?

 

The screw I referred to was the sync screw for the #4 carb. The vacuum was too high on that cylinder compared to the others and started sucking all of the ATF out of the other tubes. I shut down the engine and backed that screw off a little bit, then restarted the bike.

My YICS tool looks very similar to the tool described elsewhere on this forum. Instead of using copper tubing I opted for steel brake line. I had to use black fuel line for the rubber, as I couldn't locate any silicone hose here where I live.

I used HiredGoon's basic design for the manometer. But I opted to use a 1X4 that was only 5' long, that way I can lean the "stick" up against the left grip of my handlebars. I used clear tubing and red automatic transmission fluid, against a piece of white pine it was very visible. Worked great, Thanks Hiredgoon for posting your manometer!

I'll try to get some pictures of them on here tommorrow.

 

Cant you get the 4 bar carb syncing deal for like $40?

Why mess around making one for $15 when it can just be bough and used for $40?

I mean unless you are truly that broke and/or bored?

 

Now now, we all know that bill could easily eceed the bikes worth in the matter of 4-5 hours of time

But when your talking $15 in parts and $40 for the finished known working product

I do car audio also and I preach for people to install their own stuff. Some things are worth doing yourself providing you have the do it yourself mentality.

 

what s this carb syncing deal?
