not really sure if this is in the right thread, but anyways yesterday i rode my crf150f pretty hard for a playbike, pulled to the shop when i got back left it idle for like 2 mins to take my suit of. when i came back and twisted the throttle, it died. i coulnt pull it out of idle. the next day it will only run on choke. it dies when choke is off. its been derestricted, and thats all. i checked carb, fine. filter,fine. i dont know what to do thanks.
