[Rhodesy]

if anyone could put up the current jetting specs for a standard crf50, mine needs some tuning.

[cracka50]

needle centered and air screw 1 1/2 turns out from seated

[Rhodesy]

so std jets just center needle and 1 1/2 turns out.

can any one else offer some ill try the one above now.
also the needle i am using is out of a z50 so might be my prob. the numbers on the needle are 53050

There is no other specs. I'm pretty sure the pilot is fixed and the main is reeplaceable butyou can't get the jets for it so its prob stock anyhow. what year is it and whats been changed on it.
