ALPHA MOTO Universal Motorcycle Vacuum Carburetor Synchronizer Synchronization Balancer Carb Sync Balancing Gauge | Compatible With Honda Yamaha Kawasaki Suzuki GS KZ XS CB 550 650 750 850 900 BMW Review

Good price. Worked very well, followed instructions for calibrating gauges and adjusting throttle valves. As the instructions and reviews say, be sure to calibrate. The calibration screw is a very handy feature. TIP: For greater accuracy after initial syncing, attach each sensor to the same cylinder while riding the bike and set each to the same reading, then reconnect each to the appropriate cylinder and make final adjustments . This moves any measurement error (if any) to the opposite end of…

The tool is really good and comes with a very nice case for safe keeping. It was delivered faster than the stated delivery date. And everything looks like new. I hooked it up to the bike and it was very easy to sync all 4 carbs on an early Honda CB750 I work on. I am very happy with this item and the seller. The sensors need to be calibrated when you get them so they all read zero. Simply unscrew the lenses and turn the adjustment screw as instructed in the documentation that accompanies the…

For those who know what they are for, great. For those who don't, there are some very good instructions in my kit. I know what they are for. I received this item as described. Used them and they worked very well. A couple of rubber grommets failed, I bought others at a local hardware store. The set and counters are excellent! The rubber hose was fine (it will break eventually, but you can always replace the hose in a car). Metal adapters are good and work. Based on what they're made of and how…

This $70 tool does the job of a $200 tool. I'd almost be suspicious if it worked any better. This type of gauge, mechanical dial, not a liquid gauge, is not my favorite. But it's fairly durable and I don't have to deal with mercury. For that tradeoff, I'm willing to accept the fact that getting carbs *absolutely* perfect is a little harder. The system requires regular calibration. After all, sensors are quite cheap. Calibration is extremely quick and easy and requires a screwdriver. Indicator…

If you tried to use this ready-to-go carb balancing bike, you'd have the worst wheel in the store. Each needle pointed in a different direction with a broad border. To bring them closer I had to daisy chain them all with a common vacuum source and then adjust each one individually. A few of them were very tight. I was able to get to the point where they all crossed at about 10 inches and were close enough that between 5 and 15 didn't matter. They're not all linear to each other, so if one says…

So I can use them to sync, but the problem is that they show a lot less than the actual vacuum. but they are consistent and I was able to use them to sync. That being said, the lack of true readings prevents you from knowing the true state of your system to properly diagnose/jet change if necessary. So basically bullshit, but I missed my exchange/return window before I realized it was a defective tool. TLDR in my experience: It's like in the red on this timing tool, or I'm timing the wrong…

Pretty good carburetor timing tool. Of course it's the first one I've ever used, but it worked and was easy to use. I wish I could read a bit more and understand that it comes with its own vacuum hoses (I bought a separate hose). The main reason I am giving this product 4 stars instead of 5 is that there are things that I feel could be improved. When calibrating one of the pressure gauges, the calibration screw flew off. So I almost packed it up and sent it back because 3 calibrated sensors…
