hondaris Posted April 7, 2010 i have a 2006 CRF 450R. It has a white brothers carbon fiber pipe and the head pipe to go with it. I am going to St.Anthony's to hit the dunes and i am wondering what size of jets i need. really don't want to lean out the bike. Any help would be greatly appreciated.

idahomx32 Posted April 7, 2010 I have a 05 crf450r here in Idaho at 2500ft. I run a 45 pilot and a 175 main with a ehite brothers carbon pro full exhaust. At St A you may want to lean that out to a 172 or 170 main. Share this post Link to post Share on other sites
