Your air idle has nothing to do with higher throttle, like i said anything after 3/4 is your main jet. You cant effectively diagnose from the plug unless your doing a plug chop, to do that you need to run it where the main jet takes over and kill the engine amd pull over and pull the plug.

[ QUOTE=prismways;253198]So as I am reading up on this symptom, I see people say it's more of a running lean situation. But why would it get so bad that I'm reduced to literally having to push my bike along after it bogs to a crawl and I'm trying to accelerate from a stop.

So if I'm lean at the high end, should I increase the jet? or increase the air / fuel mixture?

My idle is perfect and consistent at 1500rpm. I do notice that when it bogs down and I am stuck on the side of road, my idle is higher at 2K but it is very consistent and no sputtering.[/QUOTE]
