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.

I was highly impressed. It was a bit time consuming making sure the tubes were cut to EXACT length, and inserting restricters, but now that it's set up it's ready to go at any time. Instructions that come with this product are very straightforward, and easy to follow. The reading it gives is smooth, and accurate. Furthermore, it does not require any calibration. The zipper case it comes with is a very nice touch, and convenient for storage. It also comes with a reusable ziptie for attaching to your handlebar. You get what you pay for. This is a very good product. I used this for my 2009 Suzuki GSX-650F. A helpful tip for anyone using this for the 2009 Suzuki GSX-650F: Be sure to disconnect the sensor harness, otherwise the bike will not start while the vacuum lines are disconnected.

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.

Worked as intended to help me sync my dual carbs on my 1996 honda shadow 600. Would recommend to anyone if you wanna learn to do the job and not burn money wt some mechanic.

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.
