Hi Gang:
I bought a new 2002 Honda XR400R about a month and a half ago. I have had some problems starting it cold with the choke open. But when I close the choke, it will start. Sometimes, it dies after idling a few seconds after starting it when it is cold.
The other day, I got 'her' started and rode for about an hour. Going downhill in 3rd gear, the engine stalled out. And then for the next hour or so, I could not start it no matter what I tried. After about an hour, when it cooled down it finally started.
I replaced the spark plug and upon inspection, the electrode was all black and sooty-and that's only after the first 30 miles in the life of the bike.
So, my main complaints are:
1). Difficult starting cold.
2). Flooded on occasion upon cold starting.
3). Will not start when stalling out when engine is warm from use.
4). Very black spark plug electrode early in engine break-in period.
I'm thinking that the pilot jet may be set for too rich an air/fuel mixture (difficult if not impossible to start when hot) as well as maybe the same being the case for the main jet(black spark plug). I'm thinking that likely, the pilot jetting is set too rich at the factory or upon dealer assembly since most of the problems seem to be with starting (mostly when engine is hot).
I would appreciate anyone's help, expertise, and feedback as to what the problem might be and how I or the dealer can correct it. The last thing I want to have happen is to be 20 miles from my car and my bike stalls out and won't start :-(
Thanks Gang!
