You won't be getting any "digital" tuning.

It is a carbed bike 33 years old.
Those kids know nothing about it.
You can buy the sync gauges for about $80.00


I like the round ones with a needle like a speedometer.
I had the Motion Pro ones with the fluid and they were awful.
Had to be calibrated each time. Got bubbles in the fluid. Could suck fluid into the carbs.

Here is how it works.
You take the gas tank off of your bike and put it on a nearby table.
Then hook it to the motorcycle engine.

Next you remove the four vacuum screw on the intake manifold.
You screw in four brass tubes into those holes to accept the rubber hoses from the gauges.
Start it up with a fan blowing on the engine and let it fully warm up.
Then adjust all of the carbs carb slide height so that all of the gauges match the #2 carb.

You are done.

All other mixture screw adjustments and float levels valve adjustment,
timing chain slack, and every thing else must be done FIRST!!!
