Exhaust Valves and Compression

I acquired an 1974 KZ 400 earlier this year and it has been my project bike. I recently noticed that when I would roll the throttle on, the bike would bog for a split second before accelerating properly. Over the course of my last ride this problem progressed to the point where the right cylinder does not seem to be firing properly if at all. The bike makes a funny buzzing noise when this happens. I was wondering if anyone has had any issues with something like this. My hypothesis is that the valves need to be properly adjusted and that cylinder is not compressing and firing. Any thoughts?

Take all the tune up steps.

I figured as much. I've got the manual, I just haven't gone through with it yet. Do these symptoms sound familiar?

Very. One thing at a time.

Adjusting the valves is one of the most basic of maintenance tasks. You should adjust them first thing before even attempting to put the bike on the road.
