Throttle Body Balancer

Very happy with my purchase, its very easy to use and accurate when minor adjustments are made.
Highly recommend this business for high tech tooling.

Happy customer

My air fuel ratio metre arrived well packed and quickly. I would happily order fromRayTechAutomotive again.

turned up quickly and works great

Carb Tuner Port Adapters

Good quality. Love that they come with a few different sizes for my different bikes.

Works great

Great piece of gear

Did the job

Hi, bought the unit to balance the carbs on my old BMW R100S. Quick and simple and the bike runs better for it. The only improvement I think would be if you could see the selected level of dampening, it can be adjusted + or - but in 100 increments (?) the instructions say. Really? I tried it but adjustment didn’t seem to make much difference, the mm hg couldn’t be read as it fluctuates too much and you can’t tell where it’s at in the “dampening scale”. Apart from that it did the job and is a lot easier than “shorting the plugs” method that I’ve done for the last few decades.

works but not without fixing first

works well once i fixed the thread in sniff stick for the o2 sensor to go in, it was threaded in on an angle and the o2 sensor eccentrically went in, without fixing it pulled fresh air in to the sensor and gave a false lean reading

Hello Samual,

Thank you for raising that. We are aware of a manufacturing issue affecting some of the sniffsticks. The problem has been dealt with and will not occur on future batches. If you still like a replacment, please let us know and we'll send up a new one.

Regards,

Ray

LambdaKing Mk II - Air Fuel Ratio Tuning Meter

Synchroking 2

Arrived today, securely packaged. Straight out of the box it worked flawlessly and made throttle body synchronising on BMW R1100S a breeze. I didn't even worry about fiddling with the sensitivity. Only thing to be aware of (not a complaint or fault). The vacuum nipples on the BMW throttle bodies are smaller than the internal diameter of the supplied vacuum hoses. Nothing that a cable tie didn't fix. Money well spent.

Excellent tool

I should have bought one years ago. Excellent quality, works exactly as advertised.

Vacuum is one of the best ways to give you a true sync on your throttles.

My only note is be careful with the vacuum nips, they are very thin and will easily snap if you overtighten over the wrong angle during removal.

Fantastic unit

Superfast shipping at a fair price. Works perfectly as described, allowing me to synchronize and set the final idle mixture on my Ducati which has an early type fuel injection system that has air bleed screws controlling the mixture at low speeds. If not set precisely it will stall and run badly, but thanks to this device it's now running better than it ever has since it was new in 2003. (Just a heads up, you do need to replace the existing exhaust bungs with some the correct size for the wide band O2 sensor, requiring a 20mm hole saw and a welder. I was able to do it on the bike without removing the exhaust.) I highly recommend this product and seller.

Good but Not

Product is quality but i was under the impression i had ordered and payed for the 4 channel balancer as I specifically checked i had but i recieved the 2 channel instead upon checking the site again i say that you had sold out of the 4 and as I couldn't find anywhere confirming I had ordered the 4 not the 2 due to how the site and confirmation emails are set up I couldn't query this either.

Hello John,

Thank you for your feedback. We're sorry to hear that the incorrect unit was ordered. Had we been made aware of the issue earlier, we would have been more than happy to assist with an exchange for the correct item.

For future reference, our contact details are readily available on our website, the business card included in your package, as well as in both the order confirmation and shipping notification emails (these emails also both include an order summery with ordered products). We're always here to help and ensure a smooth experience.

Kind regards,

Synchroking balancer

Love this product works extremely well and is Australian made

SynchroKing - Carburetor & Throttle Body Balancer

Socket Driver for 8mm Port Adapters

A/F Sensor

The unit is very easy to set up however it may require reseting to get the actual real time data. This required me to take the clip off power and then reattach. When this is done, real data starts appearing. The unit confirmed my mixture **** setup and the main jet fuel increase (richer) when throttling. However, the sniff stick did not fit inside my small diameter exhaust - CB 550K and CB 250N. I will need to fabricate a pipe for both bikes. Overall, a great unit for adjusting and understanding A/F ratio.

SynchroKing 4S mark2

Excellent tool. I have never balanced a set of carburetors so I am a complete novice at using a tool like this. I had totally stripped and rebuilt the carburetors on my 1980 Suzuki Gs1000gt so they where a long way out. It was easy to set up and the instructions are easy to follow. It took me no time to get them balanced once I figured out which way to turn the adjuster screws.

When only the best will do

That a great peace of gear, I've had it for 2 weeks and I've did my son's 2 Apilias , a mate's KTM 1290 super duke, my zx9r kawasaki and a 900 honda, love it, I'm 71
And have had a few carburetor synchronisation units, and in all those years, nothing comes close to how good this works, on both carbies and throttle bodies, it's so easy to use and accurate. Love it.

Quality Tool

So much easier and more accurate than the old school analogue jobs, and made in Aus.

Delivered quickly and works great.

Prompt reply to question

Great Product

Great product that works straight out of the box. Wish the settings would stay the same every time I reconnect it. Sometimes it takes a while for the reciever to get up to operating temperature, but that is not a problem with anything, that is just how it is. It took me a while to work out that was the 'H' warning - meaning it is still in the 'Heating' or 'Warm Up Phase' and will only show ARF percentages once at the right temperature

SynchroKing 2 Channel - Great

This device makes syncing the carbs on my boxer motors easy as.
No batteries needed.
All hoses supplied.
Great product, thanks.
