Engine stutter at high speed
Touring south america with a 2003 KLR650 with only 6K on the clock and in need of advice. When I roll on the throttle at high speed (120 km/h) I get what is best described as a ´bunny hop´ effect, which feels like the engine cutting out or stuttering. It only occurs at speeds +120. Has anyone experienced this or could suggest some troubleshooting steps.
Initially regulator was the suspect and changed, but problem still remains. Travelling with a mate on a 1993 KLR650 and we both recently did a pass of about 4500m. His bike had few problems with the altitude, aside from a little loss of power, while for me it was a real effort to keep the bike rolling, perhaps suggesting some carby issues?
Thanks in advance.
