I recently purchased a Harmonizer so that I could balance the throttle bodies on my 2011 1200GS. When it was time to do the deed for the first time, everything went very smoothly and I followed the instructions per JVB's camhead DVD (minus the fans...my temp did go up to six bars whereas its normally a very static four...but no big deal as it was still in the acceptable range). I did not, however, disconnect the stepper motors... Is there any reason I should have done this beforehand? Also, it seemed to me that making adjustments to the cable once the set screw is loose is most easily done by hand, as the wrench wants to vibrate all over the place. Is this what the rest of you have found too? Finally, once you have achieved balance at 3500 RPM, are you truly finished? Also, I was thinking next time it might be easier to mark the throttle adjustment screw with a marker so I can tighten the set screw and visually see that my positioning hasn't been compromised in the process. Anyone have any other pearls/suggestions? Thanks all!!
