Carb synchronizers

[49er]

That, I imagine, will enter the combustion chambers, foul the plugs and goo-up the intake and exhaust valves real bad. :-D

Yeah, but some of our engines would hardly be affected at all. Very little gray matter to be transfered.

Doesn't make a hoot of difference to me round or tube, but i prefer home made vacuum ones.
some may disagree but its worked for four jobs so far...

Is that green piece just a 4-1 adapter w/vavles? Where'd you get it?

It is a simple control valve for fish tanks. I imagine you can also find it at any pet stores. Good luck.

This lookes good, what did you fill it up with? Water? Mercury?

What a coincidence! I'm in the market for a new set of Carb Synchronizers as of yesterday. I just started doing a carb synch with my ancient set of mercury Carb-Sticks, when half the mercury was sucked into the engine. :shock: This never happened before, and I can't figure out what I did differently.

Oh well. I'm open to any type. I remember seeing some recommendations recently. Think I'll try the search function.

Hehe, that's why I quit using mercury carb sticks. I think some sort of ball valve wears out, and when it does..

You're draining the oil and hoping nothing is fubar.

Round guages are harder to use, but I spent nearly 10 years in Metrology, I got very good at using guages.

Cheap Carb Synchronzers

Has anyone ever used a simple vacuum gauge and moved it around from carb to carb to get the same reading at the same RPM? Does it bounce around too much to work?

[cberkeley]

It can be done, but one has to insert an aquarium type air valve in-line and adjust to restrict the vacuum flow to prevent the gauge needle from bouncing around. Also, using one gauge makes the adjustment more difficult as the adjustments all interact in that adjusting one carb changes the readings obtained on the others some.
Takes a lot of patience.

I got some replacement mercury, thanks to a generous fellow GSResources member, and had an easy time this go around.

The simple, ancient, Carb-Stix that I use, have no valves, just four tubes and hoses coming up out of the mercury reservoir. It worked fine this time at an idle speed of 1,200 rpm. Funny thing though, I adjusted the throttle cable to open the throttles for easy adjustment, then forgot to reset it. When I started the motor, it raced to about 4,000 rpm, but it didn't suck the mercury out before I could shut it off. Close one!

I saw the expensive carb sticks but got the carbtune mercury one's anyway.If you take good care of them and sync by the book,1750rpm's for my bike,everthing should be fine.It is a tool and should be used properly.

cv carb sync.

Hi, in the clymer manual the synchronizing of the CV carbs from 1980 on states that for the ( manometer gauge ) 1 & 4 carbs ,the centre of the balls are in line with the centre line marked on the manometer,while for carbs 2 & 3 the edge of the balls are under the centre line of the of the manometer, i only have the dial type guages with the damping taps ,I would be greatfull for any advice, as i thought all gauges should read the same when balanced, and wouldn't know how much to offset (if at all) the dial gauges 1 & 4 to 2 & 3.

[tconroy]

Set the inside ones a little lower than the outside.You have to set them all using #3 carb because it has no adjustment.That should get you there.

Care to share with the class how you made em? I saw some tire pressure gauges at wal-mart for 4 bucks each - can you use those? They are the round type gauges with a needle.

You synchronize them by reading vacuum not pressure so tire pressure gagues will not work.

Has anyone here ever tried a fully electronic sync tool like the Twinmax electronic carburetor balancer?
I have been looking at getting one as I am just about to get my carbs back on my bike.
No mercury to jerk around with sounds good to me.
Question: If I get a set of the 5mm adapters, can I just leave them installed with vacuum caps to make it easier next time I want to sync?
