i have a kfx450r and i got the motor done on it. nothing to crazy just a few things .( like small port job. cams. piston.)my bike hasn't ran right since. i got it re dynoed and everything. it starts fine when its cold. but once i start riding it. and shut it off. it wont start back up. like once it gets hot it doesn't start. has anyone else had this problem ?? let me know. thanks
