So I'm pretty new in the bike world, this question maybe dumb but I gotta ask. How do I know what shocks are right for my bike. Never replaced them and just got the bike after 10 years of sitting. When I ride and hit s bump I feel like my back is gonna break. There is no suspension in the shocks at all is what it feels like. So I want to get new shocks but have no idea what I'm doing. Help?

Shocks are sold by length, spring rate, and what type of mount your bike uses.

Most Japanese bikes use "eye" mounts...meaning each end of the shock has an "eye" that slides over a frame mounted stud.
Depending on what you weigh, what extra weight you plan on adding, and if you have a passenger or not, is how you figure out what spring rate you will need.
Most aftermarket shock makers have guides to help you on what spring to use.

The stock Vulcan 750 had 12.5" length shocks (measured eye center to eye center)

So, first, how much do you and whatever luggage you plan on adding weigh? What type of roads do you have to deal with? And, most importantly, how much do you want to spend. Decent shocks can cost from $200 up to $700.

I found a pair of slightly used Progressive 412 shocks for about $120. But new they are about twice that. Check out Progressive, Work Performance, and Hagon's web sites to see what's available and at what cost.

So i can't see what the damper is set on wether 1-2-3-4 I can't see those marking, Also, I have no idea if these even have oil and air in them. I feel every bump. All together I think I will load it up to about 250 lbs. it's so damn stiff..

They are stock, I was reading other forums that speculate it could just be the springs and that I do not need to add air. Also if I do refill the rear shocks with oil, what oil do I or should I use

I said to check the air pressure to see if there's too much air,which will make it stiff.as far as I know Kawasaki only made one spring for the 750.haven't heard of different spring rates.they might have,but I don't think so.

Did oil change and did not add air to shocks. Haven't rode it yet to test it out because I'm having battery problems

Matthew,I too had stock shock problems,they were old and no longer held air,changing the preload 1to 4 on top didn't help. So I was lucky to find a set of Progressive 412s from a member(thanks emtdon) for $100. They helped improve the ride as well as lowering,they were 11in. center to center. With a cheap wrench you can adjust the preload on the spring,1 to 5. Do as suggested and check out the places,such as Progressive Shocks,etc. mentioned above. Sometimes you can find a deal but I was very pleased with the Progressive shocks.As were other members when I was having problems. I didn't catch what year your bike is,mine is a 91 and rides fine now. Good luck,let us know how you decide.
