Review: Solidly built Carb Sync Tool - Used this items to sync the "starter valves" on the throttle body for my Honda ST1300. Worked well for that purpose, as they had not been adjusted for over 70,000 miles. Now my bike idles much smoother. Another upside is that I can use it on my carbureted bikes. I like the fact that the gauges have a solid feel and adjust easily. The included vacuum hoses are a reasonable length, which made this kit easy to use. It also comes complete with several adapters for various makes of carbs. FYI, the inner diameter of the included hose appears to be 5mm, so I could not use the included adapters. Instead, I had to purchase a separate set of hose barbs to connect to the unit to the throttle body hoses for a leak-free connection. I don't fault the manufacturer of seller for this, as it's nearly impossible to sell a product that will fit every application. I am hopeful that this gauge set will continue to serve me well into the future.
Review: Good quality - Solid piece of equipment, work as it should, not like cheap plastic stuff , easy hook up

## Features

- 【Superior Quality】: This is by far the highest quality Synchronization Gauge on the market, all the gauges are calibrated in the factory to preserve accuracy, instead of using plastic valve for damping control, this gauge has its own built-in damping control mechanism under each gauge, so no more missing plastic valves. There is common complaint about the over-fluctuation of the gauge, it is most likely because they didn't use the knob under the gauge to adjust the air flow.
- 【Features】:Each 2 inch gauge features 0-76cm/hg readings, all hardware are made of high grade chrome finish steel for longer life. Due to the variety lengths of the adapters, user has more flexibility in choosing the right length of adapters.
- 【Universal Application】: The set comes with both 5 mm and 6 mm adapters, will work with ultimately all bike models includes Yamaha which requires 6 mm adapters, and Kawasaki doesn't require adapters at all. And it can also be used on marine boat with proper adapters.
- 【Precision workmanship】: Not every synchronization gauge is made the same, this is made in Taiwan, the gauge itself is a precision device, without highly controlled manufacturing processes, it can never do the job right, and like other ALPHA MOTO products, we listen to customers' feedbacks and make improvements accordingly. So these gauges have the highest quality on the market!
- 【Your Satisfaction Is Our Goal】: We are confident that this Carb Synchronization Gauge is the most cost-effective one to get your job done, if you are not 100% satisfied, just contact us, we will work the issue out with you until you are 100% satisfied

## Questions & Answers

**Q: what are these adapters for?  I have a CBR600F4i and would like to sync the idle valves, but I have no clue what these threaded adapters are for.**
A: They are for 4 cycle boat outboard motors that still have carbs.

**Q: I just saw the gauge cc motor size (550, 650, 750) after i purchased this item.  will this tune a 1985 v65 (1100cc) motor?**
A: The guage don't "know" what it's connected to. It will even work on cars

**Q: Will it work on a 250?**
A: this is universal item

**Q: Will this work on a v-twin motorcycle?**
A: Its a definate maybe. There are more things that I would need to know before anyone can answer that question. Although this might be a little over kill given that you are only going to need 2 of them instead of 4. It's nice to have for if your going to use it on other bikes as well.  Generally though if it is a dual carb only one of them is adjustable in which case you can tune by sound. I have seen a few that both are tunable but not extremely often. If you can get me more info on the bike I can give you a more direct answer(year make and model would be very helpful) but in more cases than not yes this will work for you.

### ⭐⭐⭐⭐⭐ PERFECT
*by W***M on August 8, 2022*

I had a 1982 Honda CB900 F Series Super Sport in mint condition. The owner of Apache Honda in Phoenix and his mechanics, took superb care of this classic. Before he died he told me he was going to increase its performance significantly. $3000 worth of parts later the only bike to outrun me was a 1200 Ducati. A short while later I became too disabled to ride and gave the bike to my son. He had grown up with it. His wife wouldn't allow him to ride it for the next 10 years while their kids grew up significantly. Now he's trying to get it on the rode again. The Honda/Harley mechanic has taken the engine apart and done of the necessary work but insists that nobody works on carburetors anymore, especially four that need a manometer to sync them. He said he looked everywhere for a manometer without success. I found manometers everywhere I looked and YOUTUBE videos on how to use them. Now, I needed to find the right manometer. It had to the most accurate, most highly recommended, and easy to use. This ALPHA MOTO system reigned supreme! The bike runs great!
