Just making sure im clear on this.

S1 is the lubb and that is the sound of the tricuspid and mitral valves closing.

S2 is the dubb and that is the sound of the aortic and pulmonic valve closing.

Question is...a systolic murmur...that is an issue with the tricuspid or mitral valve and diastolic murmur is an issue with the aortic or pulmonic?

Also, systolic murmurs are more common, correct?

Thanks guys!

A systolic murmur can also indicate problems with the semilunar valves. If there is a semilunar stenosis, for example, there will be turbulent blood flow through the valve and you'll get a murmur.

You are correct that a deficiency in the tricuspid or bicuspid valves can cause a murmur.

I do not know which is more common, a systolic murmur or a diastolic murmur. Given the much higher pressure from ventricular contraction, you're going to have a higher velocity and hence be more likely to have turbulent flow. That's my thought but I could be incorrect.
