Pictures for "My $5 carb balancer... "

[Kypper]

I am hoping someone can repost pictures for the carb balancer explained in the topic "My $5 carb balancer..." in the FAQ. I have no idea how this is put together.

Thanks,
Jason

I found this page a while back, while doing research on carburetor synchronizing:

http://faq.ninja250.org/index.php/Is_there_a_carb_sync_tool%3F.

It's a bit more complicated, but you don't have to hold it while you try to balance the levels out.

no pic, but here's a diagram and video in the wiki

Thank you for the links. I have two different options to try. Hopefully this will fix my rough acceleration at low rpm, I am getting tired of taking my bike apart.

I need to balance mine soon, and I'm planning to do the one with two bottles.  Easier to store, and no chance to suck the water into the engine.

Check your valve shim clearances first--if they're out of spec (as mine were) the carbs won't balance properly AND the stronger side will pull water into the engine, even on the dual bottle version.

Re-bumping this. Anyone have the pictures or a diagram? All links are dead.

I have pictures of mine here.

The homebrew u-tube balancer is barndoor and far from accurate, you may as well sync them by eye or try the cig`paper trick and save yourself the time and cost involved.

Save up and buy one of these.......

They regularly show up on e-ghey etc for buttons, there really is nothing better.

Can I ask why you say the homemade tool is barndoor?  Isn't water much more sensitive to pressure changes than mercury?  If the water level is the same on both arms with the valve in the middle closed, then the amount of vacuum created by each cylinder is exactly the same.  Isn't this whole the concept of "syncing" the carbs that any tool would use, or am I missing something?

[Phil B]

I'm guessing that when you're measuring something that rapidly varies, and you are looking for "average" pressure, then a "heavier" fluid wins over something that is "more sensitive".

Then again, if you care about random spikes vs average, than lighter is better

Either way, many people seem to use oil, rather than water.

And then if you're buying stuff, instead of the mercury based one, there's some pure electronics ones.

Oddly, for close to the same price as the mercury ones. Around US$100


here's a fancy mockup for the 4cyl folks, that I think can be inspirational for us 2cyl people as well.

Good thread

I bought the motion pro synchronizer a month or so ago which was an upgrade from my homebrewed vacuum gauge set up.  I'd strongly recommend the motion pro tool.  Easy to use and just a really good unit.  I should've not been so cheap and bought it years ago.  I paid about 80 big ones on ebay.

Can I ask why you say the homemade tool is barndoor? 

Because you get far more accuracy and far better results with an instrument designed specifficaly for the job 

Ever seen a pro use a u-tube?

A tube filled with water and a gang valve can't be fit into a drawer or easily pulled out and hooked up whenever you need it, that's one reason a pro wouldn't use it. 

However, I'm wondering what physically makes a mercury tool more accurate when the two tools are measuring the same thing.

Google is your friend 

[bombsquad83]

I don't mean to be a pain, but I did google it.  I found that while the homemade tool was generally a pain to use in some cases (you have to make sure that you don't have air bubbles), it was purported to be just as accurate if not more accurate.  The only sites that I found that claim the tools are more accurate are trying to sell the tools.  If you could link me to an independent source that supports what you are saying I might be convinced.  It's very possible that I didn't find the right sources.
