Try cranking your idle up to 4k. I'm the same sprocket setup as you, -1 front and 54t rear. For me, being at 3.5k is way harder than 4k for idle wheelies - I've stalled and mousetrapped with idle at 3.5k but never stalled with idle at 4k and ever since I got Griffy's Magic star (timing advancer) I haven't stalled the engine at all. After trying your idle @ 4,000rpms, if you still want more low-end power either get a Magic Star from Andrew G. or get whatever ignition timing advancer you were looking at.
Something else that might help is an exhaust that will give some back pressure - that will give you a gain in low-end power.
I just put my magic star on last weekend and it's fuckin amazing. With the Magic star and the Nardeen saggy ass fix the F4i is becoming equal to the 636.
