Bought my 4 column Carbtune Kit to balance the throttle bodies on my 2009 Yamaha XJR1300 and what an excellent piece of kit this is. Easy instructions included on how to configure the hoses for the correct amount of damping. Adaptors provided, plus an extra set and a handy soft case for storage. I did purchase 4mm straight connectors as the XJR vacuum hoses are joined between throttle bodies with hoses and blanks. It's easier to connect the Carbtune Kit hoses to the XJR vacuum hoses as the inner throttle body adaptors are buried in the depths of looms and hoses.
Once connected to the XJR and engine warm, I could immediately see that my purchase was justified. The Carbtune Pro operated so smoothly and the easy to read scale made this job a pleasure and quick to complete. Buy direct for a better price and an excellent service.

Cracking piece of kit. Well made with clear instructions. Just the job, it was used to balance the carbs in my old Honda., which it did perfectly.

Har noen CB750 som trengte justering av forgasserrekke. God bruksanvisning. Dette produktet fungerer meget bra.

Envío rápido a España, facilidad de uso, lo compré porque en un foro de motos me lo recomendaron y fue un acierto.

Excellent bit of kit, throttle response is now crisp and smooth.Idling is now spot on as well 👍

Je cherchais un appareil à syncro de qualité qui me dure dans le temps, je pense ne pas trop être déçu au vu du prix assez bas. Utiliser pour l'instant pour mon ZZR 1100 pour essayer, très sensible et intuitif.
Top!

I purchased this to synchronise the throttle bodies on my Triumph T120 but it can be used on my classic Kawasaki Z1R as well, this is going to save money and benefit my tool collection it will be a great tool to diy and skilled people.

Fast delivery, well packaged. I found it easy to use, instructions were clear & helpful. First time balancing my carbs, this isn’t a dark art. Take your time, make small adjustments & listen to your engine. Practice makes perfect. Recommended.

As described. Good quality tool.

Just brilliant, very easy to use. After syncing engine runs smoother. Don't hesitate, just buy it

Easy to use , happy with it.

For me absolutly top tool..
Kawasaki ZR7

Everything is fine and working well, but the rubber hoses could be better quality, because after the first connection to the vacuum tubes and disconnection, the hoses become too loose, which may result in leaks, so it is necessary to cut off a little of the hose.

Worked very well

Quick delivery and a good Carbtune to my 100 hk Yamaha outboard.
