[QUOTE="spot, post: 497350, member: 37466"] Any ideas on jetting recommendations for a 2003 CR250. I have two bikes, one is stock, the other has a VForce reed valve system & a bill's pipe/silencer. Neither bike has the correct jetting. The motor just doesn't run clean. I am about 500 ft. above sea level & the temp is 30-45 degrees right now. I have tried several different combinations of jets, needles, and even slides but have not found the right combination. I have been able to get the main jet right, but the bike is giving me problems at 1/2 - 3/4 throttle. When I try to adjust the clip on a given needle, it seems to be either too rich or too lean. Please help!!! [/QUOTE]
