About this item

• 【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!

Universal Motorcycle Vacuum Carburetor Synchronizer

This vacuum gauge by far has the highest quality on the market, it is made in Taiwan. This set features 4 precision gauges. Each gauge is pre-calibrated by factory, air flow control is handled by needle and seat valves instead of knob it comes with both 5mm and 6mm adapters, will work with virtually all bike models with carburetors.

Comes with case, four gauges, adapters and hoses.

This is not your ordinary gauge set!

Made in Taiwan! Shop tool quality!

• Each 2" gauge features 0-76cm/HG readings
• Each gauge has its shut off valve
• All hardware is high grade chrome finish instead of brass for longer life, higher corrosion resistance and better flow accuracy.
• Air flow control is handled by needle and seat valves instead of knobs. This helps to resist the dial indicator "bounce" associated with many other lower quality gauges.

• All Chrome Plated Extension Tubes:
• φ3.9X100L(M5*0.8) (4 pieces).
• φ3.9X170L(M5*0.8) (4 pieces).
• Cone Type Connectors:
• φ6X10X55L (1 pieces),
• φ10X53L{M6*0.75} (4 pieces),
• φ10X60L{M6*1.0} (4 pieces)
• Rubber Hoses:φ5Xφ8X 950mm x 4

Each gauge comes with its own air flow control

The red circled control mechanism below each gauge allows the user to adjust how much vacuum gets sucked into the gauge, it will prevent the needle bounce all over the place.

• Come with a cord to hang the gauges when in use
• Primarily made for 4 cylinder bikes, can be used on two cylinder or three cylinder bikes as well
• Comes with different length of adapters to ensure the user get to these hard to reach carbs.

Essential tools for your regular motorcycle maintenance!

An ideal tool to balance multi-carbs,ensure when at idle, your bike's carburetors are all in the same RPM range, therefor each cylinder is drawing the same amount of vacuum through the carbs,result is your bike run smoothly,develop strong power.

Tuning Procedure

1. Start the engine, let it idle and check the gauges. ( Run the engine until operating temperature is reached, carburetors must be adjusted with engine warm and the choke fully open)

2. If the needles are bounced all over the place, adjust the dial under the gauge slightly, the needles will flutter, but should not oscillate too much on the gauge faces.

3. If one gauge is out of sync, adjust the adjusting screw between carbs until the sync is obtained.

4. Shut off the bike, give the throttle a few snap-backs,let the bike settles in the new setup, and repeat the process until desired result is achieved.
