Check the cam timing first. They are wrong on a lot of used bikes, even seen it on a few new ones.

Well, here's the best place to start...

8 Valve 750 Service Manual

After that you need to consider all that needs to be done. Carbs will need a complete strip and dip cleaning with all o-rings replaced.

Valves will need to be adjusted: Valve adjustment tutorial

Good luck and have fun.
