Well I'm having some issues. I got out of mx to focus on trials and let my bike sit for about a year without running or riding it. I drained the old gas and tried to start her up but she's not doing to good. I can only get it to run on with the choke on and when I flip it off the bike dies. I'm about to go check to see if there's a good spark but this is my first issue with a fuel injected bike. Not sure where to go after this if its not a dirty plug. By the way shes a 2010 yz450f. Stock motor with yoshi exhaust. Any help is greatly appreciated!
