Question about 2005 Honda CRF 250 R
Do a compression check on it a motor has to have atleast 90 psi (law of physics) to even run might need rings or possible hole in the piston

Here's how a pro service technician would diagnose a typical "no start" condition:
1) Do a compression leakdown test or compression test if leakdown is not available.
2) Do spark strength test.
3) Check fuel quality, fuel delivery and intake system.
4) In the thousands of 4-stroke engines I have repaired I have never seen any that just "need rings." And I have never seen a stock play/sport ATV with a hole in the piston. Professionals grasp snap-on wrenches. Amateurs grasp straws and knives (to stab in the dark).
