Excellent tool. I have never balanced a set of carburetors so I am a complete novice at using a tool like this. I had totally stripped and rebuilt the carburetors on my 1980 Suzuki Gs1000gt so they where a long way out. It was easy to set up and the instructions are easy to follow. It took me no time to get them balanced once I figured out which way to turn the adjuster screws.
That a great peace of gear, I've had it for 2 weeks and I've did my son's 2 Apilias , a mate's KTM 1290 super duke, my zx9r kawasaki and a 900 honda, love it, I'm 71
And have had a few carburetor synchronisation units, and in all those years, nothing comes close to how good this works, on both carbies and throttle bodies, it's so easy to use and accurate. Love it.
