you can't "replace" the Z-Bomb with fuel mixture tuning because the 1st/2nd gear thing is caused by a timing retard condition
That's what I figured, been researching it for the past couple of hours. I can't seem to find anyone in north Florida that can tune it though. So back to square one... There's a shop in south Florida, but 500+ for a tune. I think I'll just stick to the way it is now lol for that price, I've already spent way to much on this bike!
