You sure its not on choke? Also, on a typical yamaha they run liek crap if the parking break isnt completely disengaged.

 

thanks jakal i will go out tommorrow its not the choke but it culd be the parking brake

Yeup... check the parking break. When mine was still on it would get just a piece of dust on it and not disengauge all the way. I would say that is your problem since its not doing it all the time.

Next time it does it just reach up with your thumb and push out on it and I bet it will straighten right up!

Later,
Mike

 

thanks for the reply i am taking it back to the dealer tomorrow as it is still under warranty
