Grok, you sir are a genius, The harmonizer is the best sync tool I have ever owned Simply the Best
I used the mercury sticks for years and thought they were great (but could only do a non loaded sync)
The twinmax never gave the results I wanted (would not stay calibrated, had to switch the hoses to recheck after adjustments were done.)
The harmonizer is by far the simplest and most accurate, I connected the hoses did a few small adjustments, took the bike for a ride watching the readout, noticed I was real close, made a few more adjustments (very small ones) road it again with an eye on the display. the marker stays in the middle all the way., result the GSA has never been this smooth.
My hat is off to you Grok, you have made the best sync tool I have ever used
P.S. I am a Professional mechanic od 25 years
