Throttle Body Synchronization

- This is a brief video clip of my home made manometer in action, being used to synchronize the throttle bodies on my 2004 Yamaha R1.
The video was getting long, so I didn't let it run all the way to when I had the finalized synch, but it gives an idea of how the manometer works. I was very pleased with how it performed.

Very cool
Sync is not limited to carburetors. In this case you're syncing the throttle bodies so that they're all operating harmoniously. Each TB has a sync screw which allows you to adjust them (with TB #3 being the standard) all to work correctly together.
what did you do with the MAP sensor??? when i try to synch my engine does not stay idling, cause i have to unplug the map sensor....
Use a T or Y adaptor.
it will allow you to keep the map sensor plugged.
how did you make the manometer?
Can you show where you connect the fuel injected throttle synchronizer balancer and how to adjust the throttle body properly and evenly?
How do you syncbon this bike? I thought sync would be able only on carburator bikes
if there apears bubles inside. means bottom conections are not sealed properly. hapened to mine one...
what was the liquid used in the tubes? rose syrup?
Hey mate I have an aprilia rsv mille. Need to set up the throttle bodies. How do you make this system
thanks, just did that. =)
Could you tell me what materials you used to build the vacuum tube? Above all I would like to know what liquid you have used. very good worked!
CRM Motor's I used automatic transmission fluid for the liquid. Other materials were simple clear tubing and couplers typically used for home irrigation equipment.
There are a couple things that may contribute to your experience. One is that you're not using the vacuum restrictors on your manometer. Get some of those and you may experience better results. The second is that you might just have too much fluid for the length of tubing you're using. Removing some fluid may assist with this problem.
Dude look again your blind, their right at the top of the box. Fluid is correct, settles perfectly when the turns the throttle. Just another know it all.
Getting mixed info on connecting the manometer. Is this connected to the vacuum hoses you pulled off the throttle bodies or connected to the throttle bodies. If connected to the throttle bodies what do you do with the vacuum hoses you pulled off?
Thanks.
clambake28 plug the vacuum lines.
hey mate, did you need to extend the lines for your electricals / fuel line to the tank? my 03 R1 elec and fuel lines are so short i have zero access. Your take looks vertical.
That was not necessary for my '04. The lines were of sufficient length already.
mira lo que pasa es que tienes que cerrar el paso del liquido para que no lo chupe y tendras un mejor resultaso
I just did mine and I think it depends on your bike. My R6 has four hoses , 1 connects to 3 and 2 to 4. Look up how to sync throttle on 05 R6 and the guy in the forum does a detailed how to with pics. Google it. also. I hear homemade manometers aren't acurate so I purchased Carb Tune Pro it gets great reviews and it's only $100 and contains no liquid so no risk of your bike sucking it out not to mention is WAAAY smaller than a homemade sync tool.
Lv2flair do you have a link ? im looking to get a tool but i have not a clue which to get. i dont want one with liquid that i have to refill//lame

The company is British I believe but if you live in the US get it on eBay you'll get it faster.
Wich cylinder did you not adjust ? No3 ?
Correct - #3 is left static and you adjust the other cylinders to align. This is per the factory Yamaha service manual.
I attempted to do the same to my 08 R1 but the transmission fluid in the 6 foot clear lines would sort of bubble and climb toward the TB. I have to shut the bike off to prevent it from entering the TB. I have about 6 inches of fluid in each line. Any idea why this might be happening?
my guess is that you are so far out of sync that one or more cylinders is overtaking the others and sucks it up. Or you could have a leak in one or more tube/connector/test port.
the liquid for sync, what do you use? just water or else?
Automatic transmission fluid is what I used.
@@joshuaalbright ok noted thanks!
Etc?
What keeps it from getting sucked up
TwistOfTheWrist inline restrictors
and remember there 4 lines they all sucking up at same time
the constant change of the pistons'' motion ..if the manometer setup was small it might get sucked up
This machine has an error due to compensation
