My 2007 400 dies when I open the throttle. Will run if I give just a very slight turn of the throttle, no more than a quarter turn. Any idea how to fix? This is an intermittent problem. Some days I can ride with no problems.
My throttle body went out last year. It was proceeded by a month or two of "FI" fuel injection warnings and intermittent throttle response. I found a replacement part for $76 and dealer installed for $200 including diagnosis. Sounds like you might be headed down the same path.
Thanks folks. After reading the replies, I think this might be a couple of two items to look at...loose connection and the battery. I replaced the battery a few months back with a cheap one. Before replacing the battery, the scooter took a big fall after hitting a moving object. Loose connection is highly likely and with a cheap battery it is adding to the problem. I will attack these two issues and repost the results.
