rm_dave   Posted December 17, 2004 I have an 02 RM 250 that runs great but is terriblly hard to start when the temp goes down. 😢 Should I have to do some jet changes in cold weather? 😢 I used to have a CR 250 and it didn't matter what the temp was it ran and started fine. Thanks for any help. thanks, rm_dave Share this post Link to post Share on other sites

James_Dean   Posted December 18, 2004 A richer needle clip position is another option too. Moving the clip lower will lift the needle to richen the jetting. James Share this post Link to post Share on other sites

yz653   Posted December 24, 2004 Try going up 1 size in your pilot jet. You may also want to go up one size on your main. Check your plug color and make 'er tan!! 😢 Share this post Link to post Share on other sites
