Owners of multi-cylinder motorcycles with several carburetors or throttle bodies know the pain of syncing the finicky little buggers, but a tool like the Morgan Carbtune can take the bite out of the process. Available with two or four vacuum chambers for bikes with up to four carburetors or throttle bodies, the Carbtune is a British-made four-chamber stainless-rod manometer: accurate and reliable. Unlike liquid manometers, the heavy steel rod isn’t affected by pressure pulsations in the intake tract, so it’s easier to see and balance the readings.

While $82 is a bit steep for a tool you won’t use much, a dealership will probably charge you anywhere from $60 to $100 for the procedure, so this fine device will pay for itself quickly. Morgan ships it with vacuum hoses, plugs, and assorted other necessities, all contained in a slick storage case.

    …and you don’t have to deal with the mercury getting sucked into the motor or developing “bubbles” as with a cheap set of CarbStix (the bubbles are hard to get out).

    You can make one out of a 10 foot chunk of 1/8 in pvc and some fittings strapped to a board.


    Since you will be using a thinner fluid (like brake fluid) it will probably be more accurate if you are careful.

    I’ve had one for about two years. It’s a great tool to have if you have a motorcycle. It seems a little pricey but you get a good quality tool that will last you and save you money for years.

    Definitely worth it, if you use it twice you’re ahead.

    Yes, this and some air flow meters and lots of time…..young people don’t like these….no buttons to push…….

    Then again most young people don’t know what a Carburetor is…

    Tuning is a art, a science, and a passion

    pass that passion on to a young person near you…..
