So after the airbox delete, k&n filter, area-p full racing exhaust, dynojet needle + best main jet (whatever that turns out to be), what other mods are recommended to get to 33hp? This is a street bike 99% of the time with a few track days a year thrown in.

I don't ever plan on racing this bike (because I think I'd rather race a honda cb160, cb350 or rs125, incidentally).

*Edit - Oh, yeah, this is totally the thread for this conversation
So the better question is why do you want specifically 33hp? Why not just do those mods and be happy with whatever it gives you?

One of the annoying things with these motors is that the power can vary considerably from one to the next. So, with the same mods you may still see different power gains.

If you want to keep this a street bike then do the mods you've listed and call it a day.

As for Matt and those Sportisi built motors... What new products did you throw at those or are they "special" motors, not that Kirk or Brian need them to beat anyone
