With the TwinMax, balancing an intake takes no more than 5 minutes. Connect it to the vacuum ports, switch it on, start your engine, the difference in intake pressure in the cylinders is displayed on its dial.

The most accurate.

The TwinMax is a comparator. It indicates the pressure difference in each intake manifold with a single measurement. So there is no calibration error, no sensor sensitivity error, no reading error.

The most robust.

The TwinMax is a simple and robust device that is passed from hand to hand and the first examples of which have been operating for over 20 years in professional environments.

  • Highly recommended and worth doing.

    "Well today, my Twinmax arrived and I took the plunge on trying to balance the throttle bodies on the bike. Turns out it was ridiculously easy to do (thanks to all who posted info on this forum and also on you tube). I really have to get over my apprehension of all thing mechanical, so far they've all been easier than I thought.

    Anyway, after quite a few turns of the cable (I was a long way out) I now have that smooth turbine like engine back. I thought on a few rides recently that the engine was getting a bit vibey and so that's what led me to this twin max purchase. Highly recommended and worth doing."

  • A lot easier to use than a manometer

    The TwinMax is a lot easier to use than a manometer because it doesn't have to be vertical. You can hold it in your hand or set it down nearby. I set it on the under-seat storage while working, I could see it clearly while I had both hands on the cable adjusters. The TwinMax also appears to be a lot more sensitive than a manometer, giving very fine readings in vacuum differential and being easy to calibrate before use. I was able to rough-in the adjustment on the TwinMax's medium sensitivity level, and then fine tune it until I had good readings at the highest sensitivity. Today I took the bike for a test ride. WOW. The bike runs better than it has since I've owned it. It's never been this smooth, not even after what I thought was a really good balance on the throttle bodies using the SyncPro. I don't think it was very far out of balance before, but when you can get it JUST RIGHT, the smoothness is incredible. I highly recommend this for balancing the boxer.significant
  • A must for every good DIYer

    "When you've tried the TwinMax, its precision and above all its simplicity of use (and I'm not even talking about the fact that you can take it in your pocket to go to a friend's house for example!)... well, there's really no need to hesitate!!! And I've had mine for about ten years now and you can balance a big bi (BM or Guzzi) as well as a 4 in line or in V (my VFR) or a 3 1/2 RDLC.And I would say that it's (almost) indispensable for any good self-respecting handyman."
  • All considered I think it's a great tool

    "I've been synchronizing carbs/throttle plates for years with all different types of tools.. Gauges, homemade manometer, mercury carb sticks of various types and makes.. Finally bought a TwinMax (just curious I suppose) and I like it.. Compared to the carb sticks overall I think it's a good choice and easier to use.. No fluid or mercury, no problems with bubbles/voids in the fluid.. Can be used while driving.. It may not be quiet as accurate as the best tool you could get your hands on but it seems accurate enough.. All considered I think it's a great tool .. I did use the hoses and line restrictions from a carb stick set to cut any needle flutter, takes about 2 seconds for it to stabilize with the restrictions in but the indicator sits dead still.. My GS runs great.."
  • Uncompromising accuracy

    "This is what I have, the TwinMax, and to do the 4 cylinder synchros, it takes 10 minutes including the disassembly/reassembly of the seat and tank. It's very easy to use and very accurate compared to the needle depressiometers I used before. I really don't regret my purchase."
  • Super easy settings

    "For my birthday I was given a TwinMax electronic carb synchronization box. Before, I used to synchronise my carburetors on the W650 with mercury columns that I borrowed from a fellow biker, I found the operation laborious: the liquid moved over several millimeters.  With the TwinMax the adjustment is super easy, in five minutes it's done. The device is very simple: a rectangular box, two buttons and a rotary dial. You connect the two pipes to the carburetors, adjust the dial's zero and sensitivity, and then adjust the carburetor synchro screw. According to a test published in "motolégende" the adjustments are precise, it compared with a SOURIAU dyno (pro equipment)"
