Whats the stock compression on a 86 250r again?

OK I got a new compression tester cuz I didnt trust the readin the one my boss let me use and it now showing 148 cold with 6 kicks and my other bike is at 167 cold. Before I though it was 180 and 200!.

Between 170 - 199 PSI on a warm engine , open the choke and open throttle all the way and kick several times

Its a good idea to make sure the ignition switch is in the off position so you dont overload the electrical.(just in case). Also -im pretty sure it takes more kicks to get a more accurate figure.-from my experience. I kick it till it stops rising.(usually more than 6).-i know youre comparing the 2 -but still.

Yeah 6 kick on both machines and then it stops rising 148 psi aint good. I've been messing with jetting,switching pipes,reeds try to get the bike to idle and stop running rough at 1/4 throttle and its prob been low compression all along and misled because of a inaccurate gauge!
