o6 yz450f keeps dying at an idle

7 posts in this topic

i have an 06 yz450f thats been rode pretty hard,never any problems before.i think i might have gotten hot the last ride ,did the oil,cleaned the filter ,but now once i start it and ride it for a minute it want to die if i let the throttle drop to an idle then it gets tricky to start again,but if i keep on the gas its just fine. Can any tell me why this is happening and maybe how to go about fixing it?:thumbsup:

Check to see if your pilot circuit screw fell out, it happens.

Yeah, That's it. I believe it would idle a bit higher.

No, it won't idle at all. Welcome to TT.

the timing chains are crap on '06s. Pull the cam cover off and try to position the timing marks at top dead center. If you cant get it then you timing chain has stretched and jumped a few teeth. MY '06 did this same thing at about 15 hours of riding. 2 more teeth jumped on my exhaust cam and it would have been kaboom. I replace my timing chain once a year now. They are 13 dollars at any Yamaha dealer. Check it and make sure.
