you're probably running too rich (too much two-stroke oil in your fuel). check that. what are you running and what kind of engine/bike do you have?
it is a suzuki fz50. it is oil injected so how do i fix the ratio?
Travis, have you done any mods or recent work on the bike? If not, check your aircleaner, it's probably clogged up, making your engine run too rich. Do that first, it is pretty easy, before you start messing with the oil pump.

it has holes drilled in the air box thats it, how do i know if it is clogged and dirty?
Travis,
Did this just start to happen, or has it done it a long time?
Give us some history. Meanwhile, yhe air cleaner is dirty if it looks dirty, just like your socks. : )
Somewhere between the holes in your airbox and the intake to the carb, there is an air filter, look at it.
Also, check that the choke is completely off.

I'm not sure how the airbox is set up on yours, but on the bikes I've had, the airbox comes apart and there is a filter element inside. Usually you can clean the filter and put the airbox back together.
If you drill holes in your airbox, you need to make sure the new holes are on the dirty side of the filter, otherwise you might as well not have a filter at all.

i rinsed out the air cleaner a day or to ago with the hose, and when it was dry i put it back in. i have only had it for a week or so, so i dont know how long it has been doing it
did you rinse out yoru air cleaner w/ water? i don't think you should do that. use carb cleaner.
Travis,
Beginning with a ped for which you have no history is tough.
If your plug is dry and black, you have a too rich gas/air mixture, do not mess with the oil injection.
You have the following options for what is causing your problem.
Restricted air intake, dirty air cleaner or other restriction. Simple to check, remove the air cleaner and do a plug chop.
Choke is not releasing all the way, check visually at the carb.
Carb is flooding due to bad float or needle valve, check visuslly.
Main jet too big, loose or missing. Given that someone has made holes in your air cleaner, I would suspect that they may have changed or enlarged the jet.
Find out the correct jet # and if yours says it is the same, get a new one.
