Ok guys I did my compression test on both cylinders and on the right side the was blown hit from the exhaust I'm only getting around 60 psi on my gauges. And on the left which Is the.one that was blowing cool air from the exhaust is only reading around 30 psi on the gauge. Now I kno I do have a small oil leaks so I know I need new gaskets from the crack case on up. Could that be my compression problem or is it something else

both of these seem very low. I'm surprised it was running at all with those numbers.
Question, did you make sure to do the test with the throttle open all the way? Otherwise you're limiting the air into the cylinders and they won't get all the way up to pressure.
I don't know the exact specs for that bike. But generally speaking, you should be over 100 psi. and would generally want the two to be within about 10% of each other.

Yes I was holding the throttle wide open i even tired the test more then once just to make sure. I thought they needed to be at lease around 100psi to run.
