I have a 2008 KLE ABS with 44000 miles. The bike starts on the button and the automatic choke kicks in for about 3-4 minutes. As soon as the choke turns off the revs drop and the bike stalls. When I restart it it either runs ok or takes a couple of attempts and then runs ok. Very occasionally the revs will drop when filtering through traffic at low speed but when this happens the bike starts ok. Apart from this problem the bike runs just fine, no smoke, doesn't use any oil and pulls through all the gears like it always has done. Does anyone have any clue as to what might be the cause of this problem? Where and what do I start checking? Obviously I want to avoid hefty garage charges as hopefully it will be something that I can identify and fix myself.
