Picked up a 1997 sportsman 500 today for cheap. Need some help with it. It cranks and has spark and compression is 100psi. I put water in the radiator and it ends up in the cylinder. Do you think it’s the head gasket or a cracked cylinder wall. Or could it be something else. The compression has got me spoofed. It held the 100psi.

Please help me. Need this fixed by this weekend for a ride.

Thanks
