I am thinking of leaving my bike alone unless i see some good numbers. But was wondering what did you add or have done and what gains did you get.

Here's my redundant comment Add-ons cannot possibly 'make power'; power is produced in the combustion chamber, no where else for closed systems.
The bike makes 106 at the crank and 96ish at the wheel based on specs (Max. Power: 78.1KW(106.2PS)/10000r/min Source). That's your upper (but not necessarily lower) bound.
Slip-ons typically free up about 5% on a good day. A full exhaust will free up some more. Mapping/tuning/sprockets and the usual onslaught of performance mods must usually respect the upper bound max power of 106.
NOTE: In some cases, breaching the upper bound power limit is theoretically possible without violating the laws that govern energy transfer because the engine may be compromised for emissions over performance; the engine may not be producing all the power it could be producing.
Power is produced in the combustion chamber. Adding air or abetting the escape of exhaust can and will make more power. A combustion chamber is not a closed system.
Well i already have a bike with nitrous so i dont think i want to do that to this one. I looked at a leo vince track pack with headers, muffler, tuner, and i think something else too. But they sent me a dyno slip that shows the combo with upgraded air filter makes only 4 more hp. I dont expect to turn it into a race bike, I just want a little more power. But for only 4hp i will leave it alone. Otherwise i could go get a 12' zx10. Just reaching out for your experience. Keep em coming.

No, it does not. If by some miracle it did, it is not usable power because it doesn't help to turn the crank shaft. Abetting exhaust gas reduces the back pressure in the combustion chamber making it easier for exhaust gas to escape. No power is produced by that. However, it does allow the engine to produce power more efficiently, that's probably what you are referring to.
A closed system has no external influence that adds to the power creation. If it is an open system as you say, what is the source of the extra power and where is its location?
One example of source of extra power: More oxygen from a freer flowing intake. Optimized intakes and exhausts absolutely do make more power. You will not win this discussion with anyone that halfway knows what they are talking about.

yes, but you need the free flow exhaust to match. Once you get intake air flowing and exhaust you need to add more fuel. Thats where a fuel management system has to be added. Once you do air and exhaust you will be running a lean mixture. Slipons do not really increase HP. They will smooth out some dead spots, increase the exhaust sound and not really do much to the mixture. I read an article years ago and it stated that you still have the same amount of fuel and air entering the engine and you have the same amount of exhuast gasses exiting with less restriction. Most modern FI systems will compensate for this, plus you still have the catalytic convertor in line. Now adding an aftermarket air filter that is free flowing and a slip-on you will start getting into the lean mixture. Modding the airbox will add more air and lean out the mixture even more. This is where you need fuel management.
Wow, i will have to read this a few times to process it fully. I am a carb guy and am learning the injection principles. Its nice to have you guys teach it to me.
So I cant count the airbox/filter, exhaust, and jet kits i have put in. But with this injection, doing the same except I use power commander instead of dyno jet and i will get roughly the same results. The part i really dont understand is remaping and how to get the bike running tip top. Because a carbureted bike runs best stock, and injection bikes seem like they take it and want more. I just dont want to ruin a bike i plan on keeping till it dies.
Also, apples to apples the best tuned up fz8 you have seen compared to a stock one. Where do you see the gains in performance. I dont mind putting all the coolest parts on but there is that point where you think "hell, I could have bought a faster and better bike with the money i spent on getting 10 more hp". I done that with my brute force 650. Paid 6k new and have 10k in it. I just wonder if its worth it.
What do u mean by fuel management. Ecause I got a k&n air filter and did the airbox mod. I notice lose of low end torque. I think I need that fuel management you are talking about
Haha. So when i put the jet kits in and retune by moving the clip on the needle and adjusting the mixture screws, its the same concept but you use a computer instead. The jet kits are usually too lean for Indiana. So i richen them up do to elevation, average temp, and the other regional variables. Now i have to work on it with a computer and not get my hands dirty. Now the sense of accomplishment isn't there, or the burning sensation from gas spilling on your cut fingers. LOL
