[QUOTE="SRAD97750, post: 194982, member: 425"] Compression isn't a go or no-go measurement. There is no threshold of running or not. My 80cc ranges from 80-110psi My 250s are 140-180psi My 500cc with a fresh top end is expected to be 100-140psi. They are all different, but [B]typically[/B] the higher performance the motor is, the higher the compression. -BIG DAN:thumb: [/QUOTE]
