Fuel, fire, and compression are the three main drivers of any gas-powered engine. Compression is today's subject, and it can be a thick book of requirements to keep it up where it needs to be. Parts like the Yamaha Valve Cover Gasket are vital in making sure that is achieved. A good compression reading is about 140 pounds per square inch. You take this measurement by screwing a compression gauge into the holes that the spark plug comes out of. When you try and run the engine, the indicator will tell you the amount of pressure the cylinder can withhold. If it is below that magic number, you need to start looking for something that is leaking.These golf cart valve cover gaskets will fit select model Yamaha golf carts. To ensure it is the correct part for you, grab your OEM manual and verify that the part numbers match. This one is a match to JN6-11193-00. Call Buggies Unlimited today and get one ordered.
