Carb sync tool on Ebay

[Mickeymoe]

Well I'm going to take a stab at syncing my carbs, the first time I've ever done so. There is a set of vacuum gauges on Ebay, what do you guys think?

Also, I've searched the forum, is there a carb sync .pdf for Suzuki posted anywhere? I've watch a bunch of YouTube vids but they are for other bikes and most of the information consists of "uhhhh"........"uhhhhhhh", "uhhhhh"......, "go ahead and" ......"okay?"......"okay?......,"uhhhhhhh", "uhhhhhh", "go ahead and"...." etc, etc.

Those might work, but you won't be happy with them. Get a Carbtune.

There is probably a sync tutorial on BassCliff's site.

I'll probably "T" all 4 guages to 1 vacuum input to see if all 4 guages match each other and if not, add or subtract the difference when doing the sync. BTW, Could you provide a link to BassCliff's site?

Thanks, Mark

I have a similar set. It came with, and needs, damping valves to dampen out pulsations which otherwise move the needle too much. Like these, the gauges, while at rest, do not zero out identically. I try to make an allowance for that, based on the zero position at rest. It does as well as my Carbtune. The thing works just fine.

+1. The pound is low enough that the Carbtune is only slightly more expensive than those guages and it is a known, proven high quality product.

Mark already got you the link, but it's actually well-known enough that Google will find it for you. :encouragement:

Note that in some circles, it's also known as "BikeCliff's site". He plays bass guitar, and on the guitar forums, he's known as "BikeCliff".
Here on a bike forum, he's known as "BassCliff". Same guy, same site.

Emgo sells them for around 60 bucks. Now to dispel a few myths. If you know how to modulate the needles using the dampner knobs youll get the jump eliminated and all 4 at very very close to each other. As for them not being as accurate as a Carbtune...that's true in the sense of how touchy the Carbtune is as compared to the dial setup.

As for "calibrating"..heres what you do. Get them all connected to ONE vacuum source off your bike with some tees. Next unscrew the lenses and use the small brass slotted ASDJUSTER to dial all 4 to the same spot. They work amazingly well actually...just not as sparkly farkly as the Crabtune is.

I found they work very well, too. I did my calibrating just as Chuck says, although I used my MightyVac brake bleeder for the vacuum source.

I have the same set and they work fine. I will say that the o-rings that came with mine were junk, but beyond that the set works good.

If he's a bass player, shouldn't his screen name be Bass CLEF?

 

[850 Combat]

The set I got has really cool attachments for going on to the manifolds. I also have a Carbtune. I was surprised how junky the attachments are in the Carbtune compared to the round gauge set I have. Currently, I have one set in Maine, and one set in Oregon. Both work just fine. I didn't recognize the angle damping valves in this set. Should work fine.

 

[chuck hahn]

Never thought about the mighty vac as a source for calibrating the needles to each other...great idea.

Yes, that would be entirely appropriate, but his first name happens to be Cliff. :-\\\

After all, it IS the "single source" that you need. No pulsing, either. :encouragement:

I also have a set of those dial type, I replaced the rubber hoses with silicone. They work fine.

Just thought I'd chime in, I've got this similar looking set off of amazon:

https://www.amazon.com/AlphaMoto-Mo...UTF8&qid=1509119245&sr=8-3&keywords=carb+sync

I'm actually pretty surprised with the quality that they are. When I got the set they where not all reading zero but they do have an adjusting screw to set them all equal.

 

[chuck hahn]

1970..set them all equal under a vacuum load..they need to read the same as the engines applying vacuum so it makes sense to calibrate them under a load.

so how about this? [FONT=&quot] https://www.ebay.com/itm/Motion-Pro...ash=item3af07c27d1:g:LZ0AAOSwY7pZsxKx&vxp=mtr

I've had the exact same 4 round gauge setup, mentioned in the first post, for about 8 years now. I calibrated them one time with a 5 into one plastic manifold I got at the auto parts store for a couple of dollars. The covers screw off and you can calibrate them to read all the same. I use my Mity-vac as the vacuum source. Now every time I grab them to use, I re-check the calibration and in over 8+ years I've not had to touch the calibration.

To the guys who say they are junk, I wonder if they've ever tried them?

Now in the Kawasaki shop, in which I work as a mechanic, we have the Morgan, a couple of the gauge types and a fully electronic 4 carb tuner. They all work well. But for my home shop I'll stay with the $50 set I bought so many years ago. It's works just as good as the high priced stuff. Plus it comes with the correct adapters for Suzuki and Honda vacuum ports. So far I've synced carbs on Yamaha, Honda, Suzuki and Kawasaki. What else is there?

Yes, those work. I have a set here, but I don't use them because the case is cracked and some of the fluid has leaked out, rendering the gauge rather useless for any bike with more than three cylinders.

However, those will run you $85. For just a few pennies less, you can get a Morgan Carbtune. The cost to have one shipped to your door is 64 GBP. As of right now (6:34 pm, 15 NOV), that is $84.3059 USD.
Now, if you would like to have the carrying case, too, you need to add 9 pounds, so the total would be $96.1607 USD. Personally, if I were buying a vacuum gauge set right now, it would be a no-brainer, I would go for the NON-LIQUID Carbtune and be done with it.

Although I do not have any of the dial-type gauges, I have used them. A bit frustrating, even with dampers to smoothe out the pulses. I do have the blue liquid Motion Pro set, but it's cracked, as mentioned. I have a set of mercury sticks, which I use regularly. I have the official Suzuki gauge with the balls. I also have a Carbtune, so I can safely say that I have used about all types, except for an electronic one. For me, it's sort of a toss-up whether I grab my mercury sticks or the Carbtune, but as for a recommendation for anyone else, ... get the Carbtune.
