4 W/Pouch

Let me start by saying this is a great product, that is easy to use and fool proof. I bought a cheap set and it didn't work at all, needle would jump all around and not give any usable reading. This product has smooth moving rods that aren't jerky and easy to read. Syncing my throttle bodies was a few minutes and done job with this kit. I can't recommend this kit enough ! Learn from my mistakes and just buy this kit from the start, you won't regret it. 10/10 would recommend!

I was on the fence with the Motionpro tool and this one. I don't like the idea of grabbing your tool to use it and finding you have to buy special juice for it. What happens when they don't make the special juice any more? This guy is great. It is easy to set up, the instructions are simple but detailed, and the tool itself is awesome. I bought a Suzuki GS 1100E and was getting flat spots off idle, pops, normal unsynced carb junk. The bike still needs some work so the reading is not perfect, but even so, it runs so much better. Once the valves are adjusted and carbs jetted, I can do it all over again myself, which is even better. Syncing carbs is one of those magic mystery things you go to the bearded bike wizard for, according to some. You are simply adjusting the throttle plates to draw equal vacuum through them. This tool is very responsive and accurate, no calibrating is neccessary, comes with all the needed parts, and a nice case to keep it all in. If you have 30 minutes to spend, you can have synced carbs too

Works very well. Good quality & appears to be sealed off from leaking whilst in storage pouch.

The best aspect of the CarbTune Pro 4 is the scale being easy to read, and the graduations are smaller than 1 or 2 Bar. Due to the increased sensitivity it is very easy to match all three carburetors to the base carburetor. A good buy, as well as quick and easy to use.

Easy to use. It’s analog and I trust it more than the digital set I have.

CarbTune Pro worked as described on my BMW R100RT. It was very easy to balance the carburetors and setup the unit.

I purchased this because my FZ-09 developed a rather rough idle and jerky throttle. I've done everything in my power, beside this, to remedy it. It was all to no avail since I still had the aforementioned symptoms. Remember to read the instructions clearly, you have to do some cutting (with a sharp knife/razor) before you're good to go; it's not quite plug and play, but almost. After you've cut the tubes to the recommended lengths and have assembled the tubes, then it's plug and play. The results afterwards were drastic, just as drastic as my throttle bodies were out of sync ha! Idle is much smoother and doesn't sound like I have big cams and the power delivery when getting on the throttle is buttery smooth. This is quite a sum of money, but do this job once or twice and it has already paid for itself since you aren't paying your dealership, or stealership, as my friends like to call it, for their exorbitant pricing on all their services. I've attached some pictures just showing you how much they were off and how they were attached to my 3-cylinder FZ-09. Since it is a 3-cylinder engine, I just connected the 4th tube to the manometer (with the restrictor in place -- the part that you have to cut up as described earlier), but left it disconnected from the bike (obviously).

This is BY FAR the best synchronizing tool I've ever used. I used to have an old set of mercury sticks until I pulled it out a couple of weeks ago and saw all the glass tubes were cracked. I've tried an electronic synchronizer with LED lights. This beats them all. There isn't any toxic mercury or other liquid to fill it with and get sucked into your engine if it pulls a little too much vacuum when you blip the throttle. It doesn't require electricity to work like the electronic synchronizers do. You don't have to calibrate anything like some of the newer liquid based ones and all of the electronic tools require. You can actually see the individual cylinder vacuum levels while adjusting the synchronization. The electronic tools just have a green LED that tells you if the cylinders are close, in the range of 0.5 cmHg at maximum sensitivity. With this tool you can get them perfectly matched. It's a lot smaller than any of the liquid based synchronizers. My old mercury sticks were almost 3 feet long. This tool isn't even a foot long. You can store it in any position without anything leaking out of it. It comes with its own protective storage case. This is just a really awesome tool. If you try one, you'll really love it.
