CRF Deamon Posted October 2, 2005 CRF 150: Ok i took all your advice and heres what i did: Took out the baffle Took out the airbox snorkle Installed a 42 pilot jet Installed a 110 main jet Installed the new needle set clip in the center position Elevation around 750 feet average temps 60 degrees approx. My questions are: Everything I read I couldn't decide between the 115 and 110 main jet, should I have put the 115 in? Do I need to get an aftermarket air filter right away or is stock ok with all these mods? PS: My son has not road the bike yet we are going tomorrow to see how this effected the bikes performance. Thanks again! Share this post Link to post Share on other sites
