Your car is probably just effed up!
Depends on why there is no compression.
Bad cylinder head gasket or valves.
Most of the times when you have low compression on one cylinder it's an indication that the head gasket is blown. If more than one cylinder has low compression and is hard to start the you most deffinatly have a blown head gasket
Oil burning or loss of compression on any one cylinder. It may also be missing on one cylinder. A compression test will verify this.
Remove number one spark plug and squirt some motor oil into the cylinder. Now do another compression test. If the compression goes up considerably in number one cylinder you probably have bad/worn or cracked piston rings. If the compression doesn't change much you probably have burned or bent valves.
Blown head gasket. Take to dealer immediately.
Not running on all cylinders? Check spark plugs and wires Do a compression test to see if one cylinder is dead
Burnt Valve, worn piston rings, blown head gasket, or cracked head.
How do you fix no compression in one cylinder? Yes, a dead cylinder can be fixed by checking and rectifying any defective component that falls among some of the reasons that result in a dead cylinder; in order to fix a dead cylinder, you will have to diagnose the cylinder by using a compression gauge to test whether there are any cylinders with no compression. Usually, a leaking gasket.
The cylinder compression, for your Polaris ATV, is 14 to 1. The cylinder compression usually decreases as the vehicle gets older.
