Good luck with the free 78 750. If this thing has not been running then the carbs will need a good cleaning. The bad thing about the 78 carbs are the idle jets are not screwed in, they  are press fit. These will need to be removed and cleaned or your bike will not idle. You will have to carefully work them out with needle nose pliers and clean out the two pair of idle jet holes using a good carb cleaner. Hope you get it up and running, Mark

There is a lot of discussion of those press fit jets here. Search the forum for more information.
I can't help you since mine are all older with screw in jets , so I have never had to deal with them.

The need to pull the jets depends on what the carbs look like when you open them and how the bike was stored. You can use a carb tool to clean them and you can use the yamaha carb cleaner to dip them. Berrymans works ok but you have to remove every rubber and plastic piece. I have the 78 carbs and did not have to remove the slows to clean them. I did the carb tool with carb cleaner then ran seafoam through them in the gas. Idles very well other than my high idle adjustment has not been set.

The A models are not road burners so you cant really expect to carve up corners with it BUT it is supposed to be very smooth and ride decent. I would say there is nothing wrong with it at all. They never caught on however but I think that is more because so many like to shift on a motorcycle.  One good plus comes from that though. The engine and drivetrain are not likely to be beat up from a person rodding on the bike! Use the bike as a tourer and you should be very happy.
