No compression in one cylinder can be caused by several factors, such as a blown head gasket, a damaged piston, or a broken valve spring that prevents the intake or exhaust valve from sealing properly. Additionally, excessive wear or damage to the cylinder walls can lead to loss of compression. If the cylinder is not sealing correctly during the compression stroke, the air-fuel mixture will escape, resulting in zero or very low compression readings.
The cylinder compression, for your Polaris ATV, is 14 to 1. The cylinder compression usually decreases as the vehicle gets older.

a leak in a head gasket could cause coolant to go into only one cylinder.
Compression ratio is the difference in the volume of a engine cylinder between when the cylinder is at it's largest volume, compared against when the cylinder is at it's smallest volume. Gasoline engines use 8:1 to 12:1 compression ratio. Diesel fuel engines use 14:1 to 25:1.
The 2000 Mustang V6 Compression is: 9.36:1 The 200 Mustang V8 Compression is: 9.0:1
then youre running about 8.5:1 compression
Bad plug? Bad wire? Bad piston or valve (do a compression test)
Worn valve, bent valve, damaged piston and/or rings, head gasket failure.
To determine if cylinder number 1 is on the compression stroke, you can perform a few checks: First, remove the spark plug from cylinder number 1 and put your finger over the spark plug hole while manually rotating the engine using a wrench on the crankshaft. If you feel air pressure pushing against your finger, the cylinder is on the compression stroke. Additionally, you can observe the timing marks on the crankshaft and camshaft; they should align according to the engine's specifications when cylinder number 1 is at the top dead center (TDC) on its compression stroke.

The Ford Mustang GT with a 302 engine typically has a cylinder compression ratio of around 9.0:1 to 10.5:1, depending on the specific model year and any modifications made. This compression ratio is designed to optimize performance while maintaining reliability and efficiency. For precise compression readings, it's best to perform a compression test on the engine.
The compression ratio of a Nissan four-cylinder engine typically ranges from 9:1 to 11:1, depending on the specific model and engine design. For example, many Nissan four-cylinder engines like those found in the Sentra or Altima feature compression ratios around 10:1 to 11:1, which helps optimize fuel efficiency and performance. Always refer to the vehicle's specifications for the exact compression ratio of a particular engine model.
