Hi team,
I need your helps. My bike started running rough up in the mountains, back firing, spitting. I thought it was altitude sickness so I was playing with the fuel mix screws trying to get it to idle properly but it turns out it was the points. I have replaced them and set them to factory spec. As I have done with the fuel mix screws, 2 1/4 turns out.
At this point, the bike starts with the choke on but revs like crazy until i drop the drop the choke. But then any throttle kills it. As it warms up it, the idle rises to +3k at which point the throttle works. When I open the choke the idle drops to a normal(ish) level. The bike is completely stock so I wouldn't think I am running lean unless there is an air leak. I have ordered some new intake boots to be safe but spraying card cleaner on the current boots didn't change the idle.
Any wisdom to impart? I'm at a loss.
thanks
Mat
