KX 250 idles fine for alittle then starts to idle higher

[cobra265]

My 2001 KX 250 starts and idles fine for a minute or two and then it starts to idle higher and higher almost like i was giveing it gas. our fuel line was cracked big time and we did replace that which seemed to get rid of the problem but i am not to determined on that easy of a fix. is there anything else i should look at?

Most likely the leaky fuel line was causing a lean condition.
You're probably good to go now.

Check all your rubber parts for cracks,you are sucking air from someplace!
