ok heres the story. I bought this 2011 klr650 with no history from an auction. cleaned it up and it started fine but as it warmed up it would cut out at anything below about 1500 rpm. you can hold the throttle in one position and it will cut off and rev back up. very intermittent and not consistent. no popping or sputtering just wont hold rmp with drastic swings. I have cleaned carb about 14 times. I have put whole new carb kit in it. I did the 685 with mike hoping it was the compression loss but no change. I know everyone will say carb but there is no cleaning left to do. another factor could be the instrument panel was smashed and gone and i wonder if im getting some electrical confusion from that. stater looks perfect. My next idea is an upgraded carb.
