Kinda a noon question I guess. I just need to know what stock compression should be for a non reed 550 mask motor. Also 440 motor if it differs.

I checked a couple other sites and it looks like 145 to 150, but I wouldn't swear to that. OT, I'm guessing your a Folsom lake rider! Do you ever get north of Granite bay? I ride at the afterbay, I know thats trek for you, but if you ever plan on making it out this way hit me up. I go Weekdays after work, and it's usually myself, a couple fishermen, and a few wake board boats, but they all go back by the outlet, so the section I ride in is usually glass
