Thx for the input.
I had a performance problem this summer in Colorado when I got about 3/4 way up a trail that took me to 11300ft. Almost couldn't get it started again. This of course is to be expected without a jet change from sea level but wondering if the flex adjusters would even have helped. Is that elevation going to be a high speed / low speed jet change or do the flex adjusters actually change the opening in a jet orifice? Lots of questions I know but if I could see what the end of the flex's look like that might answer my question. I guess I can answer all these questions by diving into my carbs but I haven't taken the bike apart much since I have only owned it for one summer.
