need help!!!!! fuel ratio question?

i'm trying to see what fuel ratio everyone is using and what ratio is best for me to use. i have a cag with:

-ada reed valve
-ada reed spacer
-ported stock carb
-.70mm main jet
-air filter
-ada race pipe


right now i'm running 50:1 because that's what was recommended to me buy the guy i brought it from but for some reason i think i should be running something else

40:1 or 50:1 is fine

50:1 is fine.. just use good quality oil
