2013 YZ450F FI Starts, Idles, Put in Gear, starts spitting, missing?

2 posts in this topic

Hey guys, I have a 13 YZ450F. Went for a 2 week ride and bike ran perfect!!  Bike is 110% stock. Took it for another ride a week later and it has started missing and spitting when putting it in gear and ridding??


I tried new plug, fresh fuel, cleaned filter, changed oil, etc... This is really weird? Nothing has been messed with . 


Any ideas?? :(
