Or, you could not dump fuel into the air and let the budget bike meet emissions standards. That would be cool, too.

Ironically, it's the '70s crowd that forgets smog the soonest. Heck, strip that evil EFI off too and slap a Holley 4-barrel on there! Maybe if you monkey with it enough, you can get an extra 6 HP to go with 28 MPG on the highway. That'll show those stupid engineer math whizzes.

After the dyno tweak my fuel/air map was cleaner emission wise than the messed up factory map, the Suzuki engineers had my GSXF real rich at the bottom, now I only dump enough fuel over 8000 for a strong pull to redline. Getting more HP doesn't necessarily require dumping buttloads of fuel into the cylinder.

No it will not.
It only adjusts the fuel map that is already there. The restriction is built on a few more things than fuel load alone. It also encompasses 2nd flies and ign timing which the biketech gear can not modify

TPO make a good kit. Had mine on for a while so far and no probs. Just remember to ask for a resistor to remove the PAIR valve when you order. If you don't ask you won't get one. They threw it in for free when I ordered mine.

MetrickMetal also make a kit (it's for the 1250 but will fit the 650 also) and have a nice resistor on a neat mounting bracket. This guy is a motorbike rider himself. the picks on his site are of his own bike.

I meant the PAIR removal. Too many times on the interwebz you come across mods where no one posts the downside and then you have uninformed kids coming along looking for the standard list of things to do to their new bike and blindly follow it without asking why.

As an example, the old rotary engines in the Mazda RX-7 come to mind: one of the ways to significantly increase power in a rotary is to change the size and shape of intake and exhaust ports. For some, the standard answer to the "I just bought this cool old car--how do I make it go faster" question is to have a bridgeport performed on the engine. Afterwards, the engine lopes like crazy at idle if it holds an idle at all, sucks fuel like it's 1965, makes hardly any torque at low RPMs (which is the opposite of what any kid wants in the first place) and costs a fortune relative to the value of the car. Of course, these obvious and prohibitive downsides aren't posted in stark terms, if at all because advocates of porting either use their car at the track or as a dyno queen.

This isn't the same case at all, or at least not in extremes. I'm simply posting the reminder that there is a simple reason that the PAIR system exists--to inject oxygen into the exhaust stream so that more residual hydrocarbons are burnt--and not just to annoy you with popping sounds after you replace the stock can. I have no interest in the current green religious movement but smog sucks.

(Also, the popping sounds awesome once you understand that it doesn't affect engine operation.)
