to check compression you will need a compression guage (should be able to find one at any auto-parts store) then remove spark plug and grounde the plug wire install the gauge in place of the spark plug crank it over a few revolutions (hold the start button about 4-5 seconds) read gauge
"standard compression pressure (at sea level) 1,250 kPa (12.5 kg/cm2, 181 psi)
NitrousGuy says: " i am easily twice the size as R4Race, but he rides his rappy so smoothly. when i ride mine, it feels like i am really working the quad physcially, but he looks like he rides it effortlessly. you look at him, and he is a skiny guy on this big raptor, but he is so smooth that you have to do a double take. he is not slow by any means. just smooth.
