Carb sync tool STL area

[Gorminrider]

OK, if I am reading this right, when the carbs are synched, the fluid stops moving, but the levels won't necessarily be even? :-k

With the apparent volume in those bottles, you could have quite a bit of movement that could not be easily seen.

Thanks, but I will stick to my very hazardous Mercury sticks for now. If and when they stop working, I'll get a Carbtune.
Not sure how much life is left in my Mercury sticks, I have only had the set for 33 years. :-\\\

.

A store-bought manometer would be nice to have.
and that's right, this project won't necessarily be even unless you get them close before tweaking but that's not at all hard to do.
I suppose because Air is compressible a big difference in air volumes might also affect fluid inertia-and make "synch" a moving target. Taller columns would also improve it as to "time waiting" to see change.

(maybe I will put some barometers in sealed jars for a "dial-display" instead!)

Seriously, for all the time and effort that can be put into creating something, revising it, refining it and finally giving up on it,
just how long would it take to save up the $110 or so to buy a Carbtune?

That'll work if you're pretty close to begin with. If you happen to be off (I have ) the difference in the mercury level can be 10 inches. Not bad you say, the homemade job will work. The density difference between mercury and water/oil is 13.6x greater for water and 15.3x for oil. That makes a needed length of about 136 to 155 inches !!!

Hope you have the height to run it, otherwise you'll be cleaning the fluid out of the carbs, cylinders, repairing valves...............

Sci85> any luck yet? Too bad we're not closer because:

I actually found my old Motion Pro carb balancer (like the pic) in the back of my garage -- only I don't think there's any mercury left inside. Probably got turned upside somewhere along the years.

So, other that having a potential superfund site in the back of my garage, can I use an alternative liquid in place of the mercury?

Or is it the density of the mercury that makes it work right?

Sorry, but it is the density of the Mercury that makes it work right.

Not sure if you can still source any Mercury, let alone at a reasonable price.

If you can't find any, would you consider parting with the remnants of the gauge? :-k

Im an hvac tech...I oocassionally replace old mercury bulb thermostats..Most hvac supply houses have a box in the store to drop off old stats for disposal.......just sayin.

I remember a friend had a mason jar full of mercury on his desk at his trans shop -- thing musta weighed 30 lbs. But, even if he still has it, I'm not sure if I even wanna mess around with mercury anymore.

Of course as kids, we used to play with it, roll it around on paper, break it up with our fingers, make it reform into one glob -- maybe that's why we're all messed up now, heh!

I'm gonna see if I can make some sort of restrictor for it -- maybe I can still use it -- if not, sure Steve, you can have it -- but it's old and pretty beatup.

I'll let you know.

Just let me know when and how much.

That would be one possible source. It takes quite a few thermostats to fill the gauge, though.

Doubtful you can send mercury through the mail.

And no, I never got a reply from anyone in the area. I'm sure they are going to be way off. Unfortunately, I just don't have the hundred bucks left to buy one. I will eventually but not for awhile. I hope to have the bike ready for running this weekend. Can;t ride though yet as I broke my stinking shifter linkage the other day and of course, the 550 katana rod was a one off piece that's no longer available. Doh!

If you were closer, I could persuade Spyug to lend you his or at least come over and help out, but we are far away and not so quick to get out to you....

but we do work for suds.....that would have been the best part...

Hope you find a source for one soon......

Not legally. :-\\\

Homemade worked for me:

I just did two loops and linked them together with vacuum T fittings and a short piece of tube. I kept drawing air in at the fittings until I zip-tied them all.

I plan to treat myself and the GS to a new Carbtune this Christmas. Been using mercury forever but I think it's time to update. I sure won't miss those heat condensation gaps.
Personally, I wouldn't bother with the home made tool. If it's that important to save money then I hope it works. Synching carbs is a fairly precision adjustment. You should use a tool capable of the task.

How about IRL area ? with the greatest of pleasure, you could have the use of mine.

Another source for mercury is old light switches. I come across these once in a while while renovating. They are silent when used so they are easily identifiable. Any electrician might have a few kicking around as they cannot or should not be disposed of in the trash. There is a fair bit of mercury in these. To get the mercury out just drill into the housing over a jar. There may be some legal issues about having mercury in your possession. I think they have tightened the laws up on this.

I'm sure that the official tuning devices are the best but I used the bottle trick to sync my carbs (using four bottles linked together) it is very sensitive and moving the sync screws a wee bit makes a difference. The throttle is very responsive and seems to have worked well. So if you are short on cash it may do in a pinch and I'm sure it is better than no sync at all.

By the way I am in the High Ridge area near St. Louis-sorry first time I've seen this thread.

No worries. I eventually got the funds together and bought the Morgan Tune from the UK. Worked like a champ.
