My bike won't remain at idle. It just slowly dies. I already have the idle screw all the in (slide lifted open). I just recently leaned out the bike twice. And both times it would die. 1st change to: 165 main 45 pilot EKQ #3 3/4 - 1 1/4 screw 2cd change to: Taffy Mod 162 main 42 pilot EKQ #3 1/2 screw I lost that bog which is good. But it still won't idle. Also, both times I have ridden in the two jettings above, there seems to be a miss in spark at high revs (WOF or close). But that is only every now and then and not constant. Any ideas?
