I think that "missing" I was getting is actually a fuel problem. Maybe too lean? I crank the throtle and it starts skipping/missing about 1/2 throttle. No apparent air leaks. Clears up past that....3/4 to full. Since I don't have a seat, I haven't ridden yet but this is just reving the throttle in the driveway.
I have ordered the 45 pilots and not sure which direction to go with them. Leaning towards those since most peple with similar mods have them. I am also thinking of doing 1 shim and taking it from there. Hopefully I will have my seat by this weekend and I can do a real seat of the pants test.
