I sent him a few PM's and an email around the time he went dark. I never heard back. I hope all is OK with him

I'm with you, as much as I'd like to get a Harmonizer I hope all is well with Grok.

Does anybody know if Grok is still alive and kicking?
I've been trying to contact him with no reply.
I need a source of the two nipples where the vacuum hoses connect.
Mine were both broken. I only need a source for replacements.

The nipples are used in the medical industry. Try googling them. You might also try McMaster-Carr.

Thanks!

I found them. They are a Luer bulkhead connector for 1/16" hose.
Hard to buy in single quantities, but I found a manufacturer willing to send me a sample pack of 5.
They will probably be disappointed when I don't buy 500 more....

Can you post a part number? That way it's saved here for reference.

Harmonizer on 2003 R1150RT

Can anyone give me the directions for using the harmonizer on this bike?

Isn't there directions on a sticker on the back of the unit? It's pretty straightforward.
- Take bike for 15 minute ride to thoroughly warm it up (5 bars on RID)
- Remove rubber caps (or hoses) from vacuum ports on bottom of throttle bodies
- Turn Harmonizer on; wait for it to zero itself to atmosphere
- Plug hoses into vacuum ports at bottom of throttle bodies
- Put a fan in front of your bike to keep it cooling, fire it up
- Adjust throttle body big brass screws so it idles around 1100 RPM and is balanced in the middle of harmonizer display
- Twist throttle and check higher RPM balance at just off idle (~2500RPM)
- Adjust left and right throttle cables as necessary to achieve off idle balance at higher RPM. Follow procedures in a BMW shop manual or Haynes or Clymer (bleccchhh) manual to do this.

Tons of throttle balancing info on this forum with tons more details but this is the basic process you need to do.

The issue I had last summer was when I tried to do each TB seperate for best vacuum in gauge mode (I believe). I then balanced the two TB's in the center of the gauge but the bike ran like crap. I then screwed the air screw down, backed them out equal, and balanced again, ran great. So was I doing something wrong the first time, trying per directions, to get best vacuum seperately first?

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

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.
