You have to enter in the variables of YOUR bike.
I hear ya, Grn, but I'm going to agree with czar'z comment. I'm going to reverse the good chain, is hp gain or loss vs. 13.5a: I now read the dyno chart.
Fuel... oil weight, and I too agree, 0w and over 100 octane of the right stuff and I've seen hp gain with just the gas alone, so yes to that.
Air filter too, but again, I still have a faster in velocity or less restricted; so my 13.5a is going to cover that all along the power band. Look at the curve and the AFR match, right? Right.
Pipes, be it slips or single with an open thru header and muffler, of course that is direct out so, yes, more uncorking; more hp. Still, 13.5a is plenty if not stock is fine too, so any unrestricted speed out [or in] is hp gain.
A weighted 14 with a 13.5a is call this the preset. So any loss of weight is power--'to weight ratio.' So the more you take off, this still does not affect the preset of 13.5a. See the engine tuning and it has nothing to do with weight per say? But remove weight off the bike is still going to propel it faster than weighted. Thus is a speed event change, not a 13.5a event and that I have to retune for what? See how nothing has changed the tune? I send you a pc map all in 13.5a, then it's going to run that AFR.
run differently depending on those variables.I'm 165...others may be in the 200 range.It DOES make a difference.
And now we are back to this, do we really need to change the jetting per say> Do I need to change the map of the OEM and now I have to retune for less weight, or did I just experience a power to weight change? It's like saying I do not have all those fairing parts on, I have to remap my ECU for that weight loss? I've lost 10 pounds and wait, I brought a passenger along for the ride, the owner's manual says to return the ECU or has a mode for passenger jetting/fueling?
So once the swap, there is your change of tune, no pound removed. Did that sort of show theory and some wild 'Lucas Of Darkness' and it may have been more the lack of wiring up a posi ground, rather than the paper broken down in the capacitors and doping of the diode so-and-so, but every lucas part I've gone thru> works. Who am I to believe? Fallacy forward or pick a part and find out the truth times 12 british bikes goes thru one's hands and wonder just that. Where did it originate, or how?
This is where I am wondering if you are being fed some hay-in is the input, and the output is hot-and-steamy is this theory of weight and pipe and I have to call to change to a passenger setting so flash that in too?
This might be the total opposite of what I think czar is thinking, but do you see the weighted passenger vs. map AFR?
