Does anyone have experience with the Motion Pro sync tool? I'm looking to buy my first carb sync and want to get something inexpensive but not at the cost of a crappy gauge that will suck...ha! vacuum joke.
While we're at it, are the analog style ones less accurate than these tube style ones?

I have experience with all three of the Motion Pro gauges that have been offered over the years.
The analog gauges are no worse than any other analog gauge, and, like the others, they need to be calibrated before every use.
The blue liquid version is OK, but "fiddly" to use.
The mercury one worked well, but the lid over the mercury reservoir would flip up if you so much as looked at it cross-eyed, so was not very safe.
For the shear convenience and practiality of it, Get a Morgan Carbtune. The link is given in post #5, and at today's exchange rate, it's $99. The Motion Pro analog gauges are $57 from Z1.

I just got and used the motion pro blue liquid one and it was nice and easy to use for me. I don't have any experience with any others but it came with nice brass fittings. the bike is running great after using it. I liked that the restrictors kept the liquid from bouncing all over the place like the metal rod one at the mechanic shop i've seen used.

not sure if you guys in the U.S.could get them but over here in the U.K i have used a set of davida vac gauges for years, not cheap it has to be said, but 100% reliable.

"Not cheap". How do they compare to the 65 GBP that the Carbtune will set you back? :-k

I have a set of mercury gauges and I think they are the best ones out there, always correct and never need to be calibrated. If you can find 3/4 lb of mercury. I think it took about 18 thermostats to get enough to fill it up. Friend has the little ball one from Suzuki. Works nice but you must calibrate it before every use.

Trust me, you don't need "3/4 lb of mercury" for those gauges.
I have the king-size version that does SIX carbs and even it doesn't need that much mercury.

I just got through using my brand new never used mercury gauges that I have had for the last 10 years on my bike a month ago. They worked just fine. I believe it is 3/4s of an ounce they use. I got the bottle stashed already. As for the rubber flap, I just put some tape over it.
Just a word of caution, when you use the brass sync adapters, do not over tighten them, they will snap like glass. I know, cuz I did. Luckily the piece in the sync port was loose and it screwed out very easy.

1lb mercury = .93 oz of mercury. There for, I must have used .6 to .7 oz of mercury because I know I had 1lb of mercury to start. So my estimate of 3/4 of a lb was a little over but not by much. I am sure different makers of manometers use different reservoir sizes.
