Af meter

Really good product and good price I will be ordering another one soon for my mate cheers

Happy Customer

Purchased a SynchroKing with Club funds, for the use and benefit of Club members. Satisfied with the unit when first used.
Slightly disappointed that an old deal to buy both the synchroniser and the Co (fuel mixture) meter is now not offered. We would have considered buying both.

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,

Ray
