Low compression will not cause an engine to not run. It may not run efficiently but it will run. Low compression on all cylinders is caused by wear, and can only be fixed by overhauling the engine. Low compression on just one cylinder can be a blown head gasket, burnt valve, or a broken ring on that cylinder. I also depends on what you mean by "below average". An engine with lots of miles may very well have a compression reading that is below the factory specifications and not be cause for alarm. It depends on how much below specs that compression is. In any case, the only fix is to open the engine up.

Engines need fuel, compression and spark to run. You believe you have fuel so check for spark next. A faulty crank sensor could be one reason you have no spark. If you have spark, have a compression test done. The timing chain/belt may have broken if you have no compression.

Are there any common faults with the 2001 Kawasaki KX 85 As mine just stopped working for no reason?

A bike doesn't stop running for no reason. The KX 85 is a good bike. First check to see if you have good compression. If you have decent compression, an engine has to have 3 things to run, gas, fire and air. Check to make sure your carb is getting fuel. Then check to make sure you have fire at your spark plug.
