Thanks for the replies. I read the manual, but sometimes the jetting doesn't actually match the manual. I received a 170 main in a bag with the bike?

Thanks,

Joe :)

Stock jetting will always match the service manual. The 170 is optional depending on your conditions...

My 04 CRF 250 R Jetting was not as spec'd in the manual. Don't believe everything you read!

FORGET WHAT'S IN YOUR MANUAL. CHECK THE CARB ON YOUR BIKE. MY 2003 450F HAS A 165 MAIN (WHICH I CHANGED TO 168 WHEN I PUT MY PIPE ON). MY 2004 450F SAYS 165 IN THE MANUAL, BUT IT HAS A 172 MAIN. THEY DON'T CHANGE THOSE BOOKS THAT OFTEN.
