Topic: 1973 CB500 compression at 50lbs...

[Randy]

Can that be true..I took test and the gauge read 50lbs... Can the motor even run with that pressure?...It seems to run fine..

[bollingball]

Was the motor at operating temp and the throttle wide open choke open where the reading all the same on all four??

[domer]

what kind of tester are you using? method?

[xsmooth69x]

i thought it was PSI?

well pound per square inch.....

what kind of gauge says lb?

[Randy]

I meant PSI.. and its a TEC from O' Reilly's.. the kind that has the metal tube and then the flex hose and then the gauge... I haven't tried oil in the cylinders yet to see if I can bring the compression up..That will have to wait..

littlegreen: Well in short it could be true. Just remember it is more important that they are close to the same reading than what the reading is.it has been gone over a lot here TT had a good write up on it. You did say it ran fine so I would not over analyze it.
