i just got a 06 crf 250r. it starts right up with some gas. and it idles rough and when i put it full throttle fast it bog right out. but if i get the rpm up a little bit it doesnt do it. mid - top end is perfect. any ideas what it would be?

welcome to the site and congrats on your new ride! off idle bog and poor idle are typically a lean pilot circuit. as well the accelerator pump likely needs some work. the jd jetting kit we offer is excellent and will get your jetting correct and includes the o-rings for the AP mod. you can also check the jetting database in this forum and the crf250r forum for what others who aren't using the JD Jetting kit are having success with.

again, welcome.
