Jets for 400ex carb on a 250x

2519 Views 7 Replies 3 Participants Last post by  1972ct2
I am told I have a 400ex carb. No idea how to tell considering it has no stamp that I can find on it.

The two Jets that were in the carb are a 135 Main and a 38 Secondary (or pilot).

Question 1:
How can I find out if the carb is a 400ex or not?

Question 2:
Do I have the proper jet sizes for using a 400ex carb on a 250x (Assuming I do have a 400ex carb)?

Thanks in advance!
