What carb sync tool do you use?

I'm sure it's been asked before but I couldn't find it with a search.

There's a lot of tools on the market so which ones do you use and are some better (or worse) than others?

 

Morgan Carb Tune out of the UK. Works great.

 

Just use a 3# hammer. Not only are they good for torquing bolts on sprockets and swingarms, but they sync a carb too.

 

I hear the hammer is the new Slick 50.

 

Man! I'm gonna have to try one of these hammer things...

 

Sorry to derail your thread so early Rob. It was a play on this thread.

Motion pro makes a decent one $60 ish

But for hammers, I choose Estwing over Stanley.

 

No sweat Pliskin, I subscribe to the swingarm thread.


I've been looking at the one from MotionPro. It's definitely affordable. For a couple dollars more you can get one with individual dial gauges.

As long as the accuracy the same, I'm guessing the MotionPro would be easier to read?

 

I hated my motion pro as you had to calibrate it off the master carburetor before each new balance/synch. It has that :bs: man-made manometer fluid (funky blue.) Not as good as the old stuff mercury. I got a Morgan Tool thats made in the UK, have not used mine but used them else where. I think you could do ok with some old fashioned dial gauges as well, I wouldnt waste my time with the Motion Pro tool unless it had Mercury in it, flip side, they have good customer support and sell some decent stuff...Cheers.

 

I got give a +3 to the Morgan Carb Tune. I don't use it much anymore with the fuel injection, but I still dig it out when I work on the FJ. It's a great piece of kit. I had a couple of the old mercury manometers, but I really prefer the Morgan.

 

Dial gauges cuz i gottem free.......

 

Morgan Carb Tune all the way! This is coming from someone who:

First, made my own sync tool. Was extremely touchy and very difficult to use unless the carbs were already pretty darn close.
Second, borrowed and used a friend's mercury manometer... accurate, but a pain to always worry about dropping and having a "mess" or sucking mercury through the engine.
Finally, bought a Carb Tune... best $100ish bucks I ever spent for working on the bike / carbs. Do it, you won't regret it!

 

I made my own for less than $3, and it's been going on strong for seven years:

I still use my mercury carb sticks. Still the best there is, just hope I dont get a leak in them.

 

+1. Same thing I did.

 

LOL I guess we are similar in that respect. Same deal free gauges for doing a buddies bike. I see you put brass regulators on. Where did you get them?
These gauges are great for the most part. The plastic regulators take a little finesse to adjust to keep needles steady. Once that's done you can see each carbs vac and when you adjust one they show how it effects the others. Makes adjusting carbs easy.

 

I read that page. Seems really easy to make, but only compares 2 throttle bodies at a time and against each other. So you hook this up to two tb's and synch them. Then you hook them up to the there 32 tb's and synch them. Then what?

How do you know whether the two pairs of tb's are pulling the same vacuum?

Would you not have to do all the permiutations to get it right?

1-2, 3-4, then check 2-3 and see if they are the same. If they aren't the you have to make them the same, then go back and make 2 match 1 and 4 match 3.

Or... something else. What am I missing?

 

It's exactly like you said. Adjust 1-2, adjust 3-4, then adjust 2-3. Even vacuum is even vacuum, regardless of the reading is on the stick. You could even use a blank piece of wood, the lines just make it easier to see movement. As long as the fluid in the tube isn't moving, you're good.

You're doing the same exact thing you'd be doing with a 4-tube manometer... It just takes a little longer. Having the fluid steady between all carbs is the same as a gauged manometer showing equal vacuum across all four gauges.

 

Those are handy, I made a set-up like that so I could attach them to the tank bag and watch on the fly.
