Need to check my bike since I don't know if it's ever been synched. For anyone considering throwing out a hundred bucks for a carb tune you should consider a electronic manometer. As you're in that price range. I've got a Dwyer 477 and it's really easy to use and versatile. Pressure and vacuum readings in any unit there is, and will read a vacuum down to a thousandth of an inch WC. I use one regularly at work and getting the idea to use it to tune carbs at home was a game changer for me (just a tune it by ear guy before). The ability to use it for a lot of other tasks is what makes it worth the money for me.
That looks like a 2 channel manometer? More complicated to do a 4cyl engine. Nice to have the accuracy though. I have had my eye on this: https://www.instructables.com/id/DIY-Digital-Vacuum-Gauge/ I have done some PIC projects so I can do this. I contacted the author and he will have some boards to sell soon, so just need to purchase the components. Less that $100
