    You don't need guage mode to synch throttle bodies. This is turning into a troubleshooting discussion so suggest you post questions over in GS Boxers. This is a vendor thread.

    As I understand it gauge mode is for setting the idle mixture on carburettors & shouldn't be used on fuel injected bikes.
    Re-set your air screws as per factory specs and then balance. Problem solved :D

    Makes perfect sense. Thanks. Now to find the specs.

    The 2 modes (gauge and balance) are used for different functions.
    Gauge is like a standard manometer, it displays the amount of vacuum in inches of mercury.

    Balance is a differential function and shows only the difference of vacuum between the 2 ports, not the total amount of vacuum.

    To balance 2 carbs or FI ports use the balance function.

    To diagnose why you can't balance 2 cylinders, or if you need to know the magnitude of the vacuum (like check for air leaks etc), use the gauge mode.

    So wouldn't make sense to use gauge first to set the highest equal vacuum, then do TB adjust? There must be a better way to know the air adjustment instead of saying...2 and 3/4 out from bottom. By the way, I have not found what the spec is.

    In a word, no.

    Just use the balance mode.

    As long as the BBAS's are in the 'normal' range, as called out by BMW, maximizing the vacuum first is, more or less a waste of time.
    And as you found out results in poor performance.

    ps and if you want to know what the 'normal' BBAS settings are for your bike, ask in GSpot.

    Just used my Harmoniser using Grok's instructions, it was a breeze! Even given I had done a complete carby rebuild!

    Thank Grok great big of Kit!:clap

    Sorry if this is redundant folks, but I've lurked for a couple years and think these won't be resurrected. Does anyone have any 'current' information as to the future of Grok's device?

    None here, but I just looked at Grok's profile. "Last Activity: 05-24-2013 01:56 PM"

    Dang this is just what I'm looking for too!

    What a thread. Everyone's hopes up with no new harmonizers being produced (yet).

    I have two, one never removed from the box, the other used on a BMW boxer just once that will soon be for sale.

    Hi, I've used a TwinMax on my R1150GS and have been happy with that, what advantages does the Harmonizer have?

    As a former owner and user of a TwinMax I can tell you the difference is like night and day... Or like comparing a 1970's Carabela to your latest favorite motorcycle model from your favorite manufacturer. It's that much of a difference.

    The Harmonizer is much easier to use, infinitely faster in completing the job, and much more accurate in the process. I can't put it any plainer than that. In damn near the time it has taken you to open and read this post you could have literally been done with synching your throttle bodies.

    Until you've used one it's hard to grasp what an improvement it is. But the Harmonizer is so good that I bought a second one when it looked like Grok was gonna' stop making them, just so I'd be sure to have a spare.

    I never did that with a TwinMax, or any other synching solution, before. :wink:
