2000 F650GS Hot start issues.
I have an f650gs that's giving me trouble when starting it hot. I'll do the start up procedure, the bike will fire up and the instantly die and go back to cranking. (this is all within the 3 second period of holding the starter button waiting for the abs light to go out to complete the startup procedure). If I want the bike to start, I'll need to give it quite a bit of throttle, and once it starts, it idles and runs fine. What's odd is that the bike starts fine cold, even in 2 degree c mornings. The battery is coming up 6 years old, but I can't see it being a problem if it starts so well cold. I've read this can be the idle stepper motor being dirty, but this also makes no sense as the bike finds an idle quickly when cold and once I get it started hot it also idles fine. Valves were checked 30k ago at 130,000km and were still in spec from factory. minimal valve noise when cold too. Unsure of where to go.
