Fine tuned my 1973 Honda CB 750 with this easy to use tool. Packaged with care and shipped quickly.

This is the only way to tune your carbs

I used to use Uni-Syn carb tuning but now I have the ProSyn Carb Tune manometer the job takes one quarter the time to synchronize the carburetors. I use it on a couple cars and the accuracy is significantly better than the Uni-Syn method. I tuned the car with the old system and then with the four tube manometer, what a difference and it's with the air cleaner on which has a big effect!! The car runs much better, the idle is is smoother and it starts easier!! And you don't even take the air cleaner off! It's a liquid system that emulates a mercury manometer so it simple and works for less than one hundred bucks delivered.

Carb sync

This product works great and a great value to boot. Takes out all the guess work. Highly recommend.

Very good substitute

Unfortunately you cannot buy a true mercury stick because of environmental regulations but the substituted fluid used in these tools works well, expels bubbles fairly good, and you can sink it with a vacuum gauge to use as an indicator

Superb delivery time.

I placed an order for our shop at approximately 5pm(weekday). It said next-day shipping, which I've seen other companies advertise and have learned not to really expect next day delivery. I also realize 5pm is quite late in the day and usually past the "cut-off".

I was pleasantly surprised the next day when I showed up to work and had a package waiting. Less than 17 hours later and the package beat me to our office! The product was functional and as advertised of course, I'm honestly just blown away by the shipping time and ease of purchase.

Thanks Motosport!

I couldn't ask for anything more in a carb sync tool! It doesn't need graduations because you're not measuring vacuum, you're only synchronizing it. If you want to measure vacuum take one of the hoses off the SyncPro with the restrictor in place, and attach it to a vacuum gauge. I love this tool!

A: This product is specifically designed for four strokes. The readings and manometer specs are set to 4 stroke standards. Sorry at this time we do not offer a carb tuner for 2 stroke applications.
