Loose or damaged parts. Low compression can sometimes be a result of loose or damaged parts. An engine is constantly vibrating which can result in bolts and other parts becoming loose over an extended period of use. As part of your routine maintenance, it is important to check for cracks in the engine, worn gaskets, loose bolts, and spark plugs.

If you were to google "how to perform compression test", for every link that provides instruction there are just as many conflicting procedures. Some say ground the plug cap, some don't.These new 2.9-litre in-line four-cylinder four-stroke engines use a higher compression ratio to help them deliver more low-end torque. Suzuki has also tweaked the four-cylinder engine's offset driveshaft to move it forward, reducing its vibrations and improving the balance.
