Denbow, sorry if my first post was confusing. I'm looking to create a linear level of acceleration from bottom to top, which existed before the mods although with less umph. Beemerrich is right though, it's all relative and perhaps it does just feel flat in comparison to the increased power at the top end. Everything I've done on the bike so far has been seat-of-the-pants measurements since dyno-tuning isn't really something I can afford right now.
I've selected some of the cheapest and easiest mods for the bike for now while money is tight, not to say I wouldn't love to bore the cylinders later and put some shiny velocity stacks on the intake.
Sounds like getting an AF gauge would be a great way of optimizing the tuning for me. I've also thought about adding a polaris bellmouth to the snorkel hole to smooth the air, or even cutting out the airbox DIY ARK style. Keep hearing this kills your MPG though, since you gotta balance all that new air with more gas.
