    2003 xr 80 jetting

    by jbowens » Tue Mar 09, 2010 8:30 pm

    I just got my daughter a 2003 xr 80 for her birthday, and I'm having some issues with a hanging idle. I'm guessing it's a partially clogged pilot jet, and I will be taking the carb apart to clean it. While I have it apart, I would like to get the jetting correct. It's completely stock (I can remove the snorkel and any other restrictive parts you guys recommend). We ride at sea level and the average temp is around 70F. Please, let me know what free modifications I should do and what size pilot and main jet I need.

    Thanks,

    John

    Here's a good thread with a lot of info that you can use.

    I found that some of the part #'s in the thread are obsolete, so you might need to call a local dealer to find alternate part #'s.

    any knowledgeable dealer should be able to help.
