WHAT THE FUCK
I am totally stuck again. Last Friday the 90 jet and W9 needle seemed a little rich but close to perfect. Today I started it for the first time since the rainy weekend and it stutters and misfires at WOT--- like minor, intermittent 4-stroking, it won't break into full rpm-land. Uhhhh, did a coil or condenser start to die? It still idles great and doesn't start stuttering until I'm in the upper circuit. !!!!!!!!!!! so frustrating.
I figured... well maybe it's cuz my plugs are black. So I downjetted a ton, down to 76 and it still stutters and misfires even though my new plug looks good. what the fuck?
I've been trying to tune this thing for a fucking week and I'm totally stuck. I haven't a clue what to do, I have no wheels.
