ALPHA MOTO Universal Motorcycle Bike Vacuum Carburetor Synchronizer Synchronize Carb Sync Gauge Cb Kz Gs Xs 550 650 750

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.

Worked great. Good adjustment for reducing the flutter in the needs to get an accurate reading. Well worth it.

Solid piece of equipment, work as it should, not like cheap plastic stuff , easy hook up

Works perfect. All gages read accurately

Works great, better than more expensive competitors, you certainly get what you pay for.
