Well I left my bike in the garage for about a week and didnt ride it or touch it. Then I took it out and it took me like 45 minutes to start. So I thought it was just from it not being started in a week. Then the next day it took a long time again to start. Then when I finally get it started it like revs real high so I set the idle down low. AS soon as i put the choke in the bike stalls. I replaced the spark plug cleaned the carb and rejetted it to the right specs. Now the bike just wont sit and idle i have to have the idle up real high so it wont stall. Oh and the bike is a 2004 crf250r.
