How much compression should a 2007 kx250f have in psi?

A 2007 KX250F should have a compression reading between 180 to 220 psi when measured with a compression tester. If the reading falls below this range, it may indicate wear or issues with the piston rings, valves, or head gasket. Regular maintenance and checks can help ensure optimal performance. If you're experiencing performance issues, it's advisable to diagnose further or consult a professional.
