SynchroKing - Carburetor & Throttle Body Balancer?

Works well on my 2023 Yamaha MT09SP, had to replace all the rubber hoses with a smaller diameter 4mm hose to suite my bike. Would recommend the product.

Road tuning with AFR

Postage was quick and the product worked just as it should, I added the exhaust mount and it worked perfect for what I wanted to do

Great service, Great product

Awesome service and easy to get back up. Ray is very accommodating and easy to work with.

Excellent Product

I bought these to synchronise the throttle bodies on my 2005 Yamaha FJR1300. They are so simple to use. Self calibrating and immediately showed that two of the bodies were out of synch. With a couple of tiny turns of the vacuum screws everything came back into synch. The only very minor thing I found was that the black vacuum tubes that come with the SynchroKing are fractionally too big in internal diameter to get a good seal on the vacuum ports of the FJR. This was easily fixed with some smaller bore tubing whos external diameter fits snuggly inside the SynchroKing tubes and then the internal diameter fits around the ports snuggly. Litteraly a few cents worth of tubing to correct it which might be worth considering adding into the kit.

Must have tool!

I have used mercury sticks for a long time, and have had good results. Then I spilled the mercury (what a lot of trouble to clean up) so maybe time to move into the modern age. The Synchroking is a must have, simple to use, powered off the bike, no spills (no toxic clean up) and wow is this thing accurate! I wish the synchroking was available 30 years ago. I have used it on several bikes now and the customers all say their bikes run smoother that they ever have!
If you are on the fence, stop worrying and get one, you will not regret it!

Definitely worth the money

What a great little unit. Made the job super easy. Now that the bike is set up for it, it will be a breeze when I need to check it again. Transformed the bike from “ yeah baby” to “OMFG” within an hour. Highly recommended!

Wide band sensor

Replacement sensor worked fine. Wish the wide band tuning meter unit went to 2 decimal points instead of only one decimal point.

Works well on larger bore exhaust pipes partly protecting the oxygen sensor

Offers versatility to work on engines that do not have welded sensor nuts. However it is too large a diameter for some mcycle exhaust pipes and would prefer it in steel with a smaller OD for this purpose in steel not aluminium. Will have to manufacture my own until Ray can offer one.

Excellent

Excellent product. It did exactly what I needed to do and was easy to set up

Brilliant and easy to use

Worked perfectly, haven’t synchronised carburettors for many years

Carb sync tool

Excellent makes the job very easy

LambdaKing Mk II - Air Fuel Ratio Tuning Meter

Lambadaking MkII

There communication and after sales service is bad. I have called and sent emails in regards to a problem I have with the unit but unfortunately they will not return calls or emails. Very disappointing as I am supporting an Australian business and one of this the reason I purchased. Also purchased carburettor balancer and have had no issues with that at all its a great unit so that is also why I purchased agin.

Hello Shawn,

I think you might have missed our message on the 17th of January in response to your query about the sensor being 'a lot larger than anticipated'. If you still require assistance feel free to contact us on info@raytechautomotive.com.

Regards,

What an excellent product does what it
Was made to do highly recommend
This company and products

A must have tool for the motorcycle mechanic

The SynchoKing was so easy to use and the results are instant. Synchronising multiple carburettors has never been made easier.I should have bought this great tool years ago.

Excellent unit

After trying various ways to tune my twin cyl bike the Synchroking help with diagnosis.
Even after then trying by ear I rode the bike for a day and still wasn’t happy. I was out in the higher rev range which the Synchroking helped out nicely.

SynchroKing - Carburetor & Throttle Body Balancer

Great product, fast delivery, so easy to use. Thank you Raytech
Wish I knew about this product earlier. The time I've wasted previously, trying to get fuel systems balanced I'll never get back.

SynchroKing 4S MkII (4 Channel)

Really good product. Made it easy to balance my (4) throttle bodies. The only issue I had was that the diameter of the supplied tubing was too big to fit the vacuum stubs on the throttle bodies of my bike (GSX1400). The stubs are pressed into the throttle bodies on this model - ie it doesn't have screws to remove and install the supplied nipples. I had to join the supplied tubes onto smaller tubes (about 3mm ID) to fit my bike. I note on another bike I own (GSXR1100) the supplied M5 nipples will **** into the carby's and the supplied tubing will be fine.

Sniff stick

Great tuning tool. Took the guessing of mixture settings out of my 350 chev engine with a large camshaft. Thankyou for good service . Cheers

Worked Perfectly

Syncronised the carbies on three bikes (4 cylinder engines) this week after receiving the SynchroKing. Very happy with it and made the job some much easier and quicker. I would recommend the SynchroKing to anyone who tunes motorcycles.

O2 sensor was fine

Australia post let myself and RayTech down taking 21 days to deliver my part after charging me $17.00 air freight which should have taken max 4 day’s delivery.

Great gadget

Worked a treat … far superior to the analog gauges etc

Great product backed up with excellent service

Very easy to use and has really assisted with carby jet tuning. The first unit received was faulty and within 24 hours another replacement unit had been sent out. Support was responsive and easy to deal with. Fantastic to see an aussie product backed up with great customer service.
